Sounds plausible to me.My .02:
A weak starter that hits on the compression stroke will often not have enough strength to get past it.
The same starter, hitting on the exhaust stroke, will be allowed a "running start" before it hits the compression stroke.
This is (likley) why it started after you attempted to roll start it.
Went to Advance Auto and battery checks out fine. So does starter and alternator, but the handheld diagnostic machine they bring out to the parking lot performs only very basic testing of the starter.
