I think that the bat now causes corner bound on ground hit actually. At least, if I'm reading it correctly and Jin 214A causes it. because they both say "画面端バウンド", which means "screen edge bound".

it looks like 6C just doesn't cause the enemy to float on ground hit, even on fatal counter
EDIT: because oh my god, Bat on CH shoots them straight above you, and you can follow up anywhere
