Touchback or Safety?

[Kirby]

Rom Gilbert has an interpretation for NCAA in Pre-Season Quiz #10 on this same play. He rules touchback as forced touching only applies during kicks.

Here is Rom's ruling:

Initial impetus is considered expended and the responsibility for the ball's progress is charged to a player if the ball comes to rest and he gives it new impetus by any contact with it. The ignoring of this type of touching only applies during scrimmage kicks that have crossed the neutral zone and free kicks. Although it perhaps seems unfair to charge B77 with new impetus, that is the rule.

So, it looks like the NCAA ruling does not go outside of rule support but the FED ruling does. Interesting.
