I think it is as simple as it appears. No run can score if 3rd out is batter-runner not safely reaching first; and it seems clear that BR was illegally assisted. In softball, we have a new inning.
I believe baseball states all forced runners are also awarded the next base (as opposed to may advance without liability to be put out UNLESS....). That may be where bluezebra Bob got his thought process.
