Oh Brett, you do make me laugh. it is, to be fair, a very awkwardly posed scene. And it only gets more awkward looking when they start floating... I kinda feel like it would have worked better if they'd been standing.
I feel a bit like Johns gets the basics if WW character but has a lot of trouble getting it down on page. There's been some good moments: wanting to help Cheetah, comforting Cyborg, her little speech to Darkseid about too many people thinking the world is there's etc... But I think he has trouble reconciling this more caring, compassionate side of her to her more warrior-ish side. He drops these little moments of her more caring nature but they're crushed under the fact that he's got her talking about how she cuts peoples heads off and had her try to kill Green Lantern (and you will never be able to convince me that she wasn't trying to kill him). Her freak out over Steve was hugely out of character. If it had stopped at her thumping Green Lantern and perhaps some heated words then I would have been fine with it. That would have been okay. But having her go after him, and having her try to hurt him, that's just not Wonder Woman.
It's not as though when Zola was taken Diana punched Hermes in the head and then snapped Lennox over her knee. Or when Lennox was gravely injured by Artemis she didn't beat Hermes senseless and proceed to destroy the surrounding town. Of course she didn't. She's Wonder Woman. She has better sense than that and more control. She calmly got her shit together and did what needed to be done to save Zola (both times). She choose to leave Lennox behind, which must have been a hard thing to do since he might have needed her help as well. She made adult decisions like an adult, and like the superhero I know she is.
The closest in Azz's run to a Steve-in-trouble style freak out was in issue #7 when she tried to liberate the slaves and threw Hephaestus through a wall. And even that was minor in comparison. She didn't beat him his hammer. She didn't whip him through the workshop with the lasso. She was angry, she reacted, and then she was sorry and had a little cry. This was also the result of a lot of emotional crap building up for her (mother just died, people turned to snakes, Zola been taken and then some dude tells her that her family are douche bags) so it reads a bit more realistically. Especially since there is no bloodshed. At least to me it does.
I think Azz has a better grasp on Diana's character, and is better at balancing all of her different, and often contradictory*, characteristics. His Diana is more likely to choose to not fight than she is to engage in combat, she doesn't fight Poseidon, she doesn't fight Hades; whereas Johns' Diana's first answer to any problem seems to be to hit it. I'm a little surprised that rather than walking away form Superman she didn't punch the poor dude in the nuts.
I'm not too sure if the disconnect is a problem though. This is, unfortunately, par the course for Wonder Woman. Writers struggle with her. I'm honestly at this point more baffled by the massively different voice used for Diana in Batwoman than in JL. I found her sudden formal speech patterns and the way she waxed lyrical about fighting and slaying beasties to be really off putting. It really didn't fit in with Azz's much younger tone of voice that he's been using, whereas I would say that Johns' does, though it reads like it was written by a fifteen year old on their lunch break.
*I always find this to be an odd criticism of the character, that she's contradictory in her character. Aren't we all? Isn't that what makes us interesting? I feel like it's an excuse used by people too lazy to enjoy a complex character, or worse by writers who are blatantly admitting that they are not good enough to handle a complex character.
