Why would you say something so irrelevant? Did I make such an argument? No.
You clearly don't understand
Imagine if you could make an invisible floor under your feet whenever you wanted, now imagine doing that while falling, how in any capacity would that make you fall faster?
I think you are the one who isn't understanding. They use reishi to make footholds in the air. If they are going downward, they glean still make footholds which let them kick downward. See Ichigo starting his descent, see Grimmjow after roundhousing Ichigo into Karakura.
Your issue seems to me that you are treating it like a human is upside down and thus would fall away from any floor ignoring the fact these guys are far and away faster than gravity.
The argument for him coming from above still doesn't change whether they had already landed as Renji was with Ryoka and she came from directly above Rose and thus Renji doing so as well makes the most sense.
