Over the Back rule has changed

"I had a talk with that referee after the game and he said that the rule had changed and that over the back was not a foul now if you don't touch them." I said that surely that was not exactly what he said. "Yep. He said over the back used to be a foul whether you touched them or not but now it isn't."

Was it ever a foul? (MTDSr?) Surely at some point it must've been for the misconception to grow this large.
