Obstruction on defense

[rocket4]

Situation: R1 @3rd,D5 playing 6-7 ft off line and 8-10 ft up. R1 takes lead off with release of pitch and returns due to result of pitch being called strike/ball/foul. In act of returning to 3rd base, R1 and D5 have contact though D5 has maintained her said position. BU gives obstruction warning to D5 and coach. Next pitch same situation, same result, BU calls obstruction on D5 and awards R1 not base she was going to but the next base which plates a run. This was college D1 game. Was this umpire correct in his interpretation of the rule in either/or the obstruction call since R1 was way off the base path, and the award of the base she was returning from?

Here are the NCAA obstruction rules with the described effect:

9.4.2.6 A fielder shall not at any time obstruct a base runner rounding or returning to a base.
9.4.2.7 A fielder shall not position herself in the base runner’s line of vision to intentionally distract her or intentionally prohibit her from seeing the release of the pitch.

EFFECT—(9.4.2.6-9.4.2.7)—Delayed dead ball is signaled. The umpire shall issue a warning to the offending individual and notify her coach. Subsequent violation of the same rule by the same individual shall result in a one-base award to the obstructed base runner and each other base runner forced to advance. The awards shall be to the base beyond the base where obstruction occurred unless the base runner safely advances farther on her own, in which case no award is given.

To start, you cannot have obs on a foul ball. If F5 was where you stated, this sounds more like the runner was making intentional contact trying to draw the OBS.
