OBS Revisited...again

[JEL]

NCAA game this weekend. I will try and 'splain best I can with all the info needed.

Runner at second, SS is set up on the line from 2B to 3B, not moving in with the pitch. Runner is leading off with the pitch at an angle of about 20 deg towards the rear of the line. Runner leads and returns the same way for 3 pitches.
On the fourth pitch she breaks for third in the same manner, running sort of an arc and is thrown out at 3B for the third out. Offensive coach (in more of a "fishing" manner) asks "why didn't I get OBS on that play?".
I told him "coach I was watching closely because of where SS was set up, but your runner left 2B in the same manner all 4 times, and never slowed or altered her path, I didn't see her obstructed in any way" The SS BTW ran behind the runner towards the 2B side to back up the throw. The coach didn't argue, or question further, and seemed to be OK with the explanation.

The question I have is, Would any of you construe the runners initial leadoff toward 3B (at the 20 deg angle) as being obstructed?
