Don't know about NFL, but NFHS...
NFHS rules:
R cannot run into or block, tackle, or charge the kicker except when:
a. Contact is unavoidable because it is uncertain that a kick will be made
b. R touches the kick near the kicker and contact is unavoidable
c.Contact is slight and partially caused by movement of the kicker
d. R is blocked into kicker by K
Each of these is a JUDGEMENT CALL by the R. The rules don't say anything about the kicking foot on the ground.
As an R, I'm looking for vulnerability of the kicker and any contact. If R hits K, most often I've got a call of some sort. I'll toss the flag unless I see R touch the ball first. If so, I give the "tip" signal so everyone knows the ball was touched. I can't say that I've ever seen K move into R and negate a foul due to his movement.
