You won't know if R1 is staying at first until the rundown is over. As long as he is there PU has the rundown...all of it, once he gets in position:

Foul territory about half way between third and home to begin with and then adjust as necessary to see a play.

i don't have my Red Book with me, but this is the mechanic a New York Penn umpire told me that PBUC wants to see.
