Well... depending on cam timing, valve overlap and whether it's batched fuel or not...fuel. Since the intake valve opens before the piston has reached TDC, There is a slight amount of reversion, Isn't there? Also, in a batched injection setup with multiple squirts, isn't there a possibility of drawing fuel in from adjacent runners? Granted, It's probably negligible with a manifold with longer runners.
I would think that airflow that's inherently unstable as it passes the injector would aid in atomization. It's just a thought, I could be wrong. I know it makes more of a difference post injector.

After thinking about it a bit, I guess the scavenging effect of the exhaust pulse would tend to negate the reversion theory, wouldn't it. Anything above an idle rpm would probably keep everything flowing in the right direction anyway.
Forget I said anything. Still nice work though.
