I don´t ususally pick Johnny, but when I do I use the beard variant, just for making him look at least a little bit different from his Xrd desing and go accordly with the rest of the cast. Like, some of Strive roster had some aspects of their desings changed, like Jack´O hair color and Ramlethal more clothing and a different hat shape, and others got a complete redesing, like Sin and Ky while Johnny, Potemkim and Baiken are almost copy and paste from Xrd 💀
If you do a bt exactly as you jump over someone, you will have your back turned, but backturned bts have the same mechanics as the forward facing ones. I don't know exactly how it works, but that 842 was a low and side switched, even if it looked wacky
Backturn BT. If Goldlewis inputs a Behemoth Typhoon on cross up the moment he lands, he doesn't turn to face his opponent and gets the opposite input. While it requires setup with drone for it to be done safely, it enables him to do unreactable high lows since BT 862 (the fast overhead) looks nearly identical to BT 842 (the slow low) if one or the other is done while Goldlewis is facing away from his opponent. In this case, Dentran hit BooShy with a backturned BT 842 which looks like an overhead, but is still a low. The cherry on top is if this particular BT hits this way, it sideswitches for a full combo.
