Thought I knew this, but now I'm doubting myself...

Yes, and this is likely what confused Bama's partner.

But this was a force situation. And R1 must vacate 1st until the BR is out. Then R1 could return to 1st.

Bama was correct that R1 could have been tagged while standing on 1st base... then the base could have been tagged to get the Batter-runner out. If the base is tagged first then R1 is safe... having never vacated the base.
