NFHS thrower problem

[Damian]

Last week, I had a spot throw in on the end line. After throwing the ball in, the thrower ran along the baseline out of bounds and came in the other side of the lane while the ball was being passed around the top to get probably back to him.

I immediately called a violation. This year, there was a rule change stating that a player that was legally out of bounds and did not return would be charged a technical. I knew the rule, but it just seemed too severe. So, I just called it using last years interpretation. Has this happened to anyone else?
