Last second ending question

[StudyingFutureZebra]

This question comes from the first college football game played during my lifetime, and I'm wondering what would have happened if played under today's rules.

Michigan trailed Virginia 17-12 with 4 seconds left. The Michigan receiver caught the ball in the end zone and was ruled in bounds for a touchdown. Here's the video (https://www.youtube.com/watch?v=JfQIzPKrj3Y) and I can't tell, but do you say the left foot was in? IIRC, when one foot has to be inbounds, it has to be the first foot to touch the ground, so if that left foot was out of bounds, the right foot would have been irrelevant, correct?

The other question I have is if a game ends on a touchdown, such as this game that ended 18-17, does the losing team have the right to force the winning team to attempt a PAT, as if it's blocked, they can get 2 points and win the game.

If the conversion could impact the outcome (like it would here) there has to be a snap.  Michigan would likely just take a knee.

I wondered about the rule today, as apparently in 1995, the losing team after a last-play ending could just admit defeat and forgo the extra point, as Virginia ended up doing. What's cut off in that video is that the R comes on the PA after the jubilation had died down and announces, "Virginia has elected not to try the point after; the game is over."

wording of the rule in 1995:

8-3-2-a
The ball shall be put in play by the team that scored a six-point touchdown.  If a touchdown is scored during a down in which time expires, the try is mandatory unless the team behind in the score leaves the field of play.

That was a rule change effective in 1995.

In 1994 it said:

The ball shall be put in play by the team that scored a six-point touchdown.  If a touchdown is scored during a down in which time expires, the winner of the game has been decided and both coaches agree to forgo the try, the period is not expended.
