However, the opposition's illegal motion penalty was waved off and the opposition was awarded possession and got an additional 15 yards and a first down.

Correct me if I am wrong, but the home team should have received possession and lost 15 yards from the spot, right? Because the play was blown dead, there should have been a turnover.

You're making this play more confusing by using home and opposition instead of A and B or K and R, but it appears that you have the situation correct.
