NCAA Obstruction

This exception simply relieves the "between 2 bases" exemption to the OBS rule and allows the umpire to rule the obstructed runner out if, in the umpire's judgement, that runner would not have returned safely to the base left too soon had the OBS not occurred.

I understand the ASA exception and I think I understand A.R. 9.4.3.5. Am I correct in my scenario below?

R1 is on 1B. A fly ball is hit to the outfield, and R1 leaves 1B before the ball is caught. R1 is obstructed by F4 en route to 2B. R1 realizes she has left early and returns towards 1B. The defense completes a live-ball appeal by throwing to F3 before R1 reaches 1B.

NCAA: R1 is out. Full stop.
ASA: If in the judgment of the umpire, R1 would have been out absent the obstruction, R1 is out. Else, R1 may be protected by OBS.

Edit to add: Is R1 still out if F3 commits the obstruction at 1B while about to receive the thrown ball? (NCAA)
