Did he make the right call? He certainly didn't make the wrong one.
I don't think the debate is about whether its an accurate call rather is this one we would no call. My guess would be at that level they (coaches, players, maybe even the officials administrating body?) are expecting that the threshold for contact/advantage be higher than that before a call is made.
On the flip side maybe if more of these were called at all levels we would see less selling of contact to try to get calls . . .
