In what way was the BR affected? Poor baserunning put her in jeopardy, not the obstruction on R1. If R1 is legally put out (absent obstruction), BR is safe. If R1 gets back safely, with or without obstruction, BR is out when tagged.

I agree...I was just trying to state the unasked question that I think was the point of the OP.

After thinking about this play a little longer, I came to the conclusion that R1 started this whole thing by "rounding large" and getting herself in a rundown. She was (potentially) bailed out of the rundown by the obstruction, but if she had not made such a large round of second, it's probable there is no rundown and B/R stays at first.
