Momentum on a free kick

I agree, sounds like an IW.

Just to expand on that a bit: 4-2-3c dictates that R has the option "to accept the results of the play at the dead-ball spot or replay the down." The result of the play would ordinarily be a safety (R carried the ball into their own EZ, where it became dead), but the momentum exception applies here, making the result of the play R's ball at the R2.

The other option — replaying the down — would be a rekick in this instance. The K coach won't be happy about it, and a beanbag helps to sell this call.

I also agree with HLinNC: if the covering official has any doubt about possession, then it was still a kick when it crossed the plane of the GL, resulting in a TB. In that case, he got it right.
