Based on my experience, this is true, but it doesn't always snap where you score it
. (I was lazy, it was 1/4 inch makrolon, I scored it with a dremmel.)
The groove wasn't of a consistent depth, this was made worse by the fact that melted debris had re-hardened to fill in other parts of the groove. After (ALMOST literally) jumping up and down on it for a while, it snapped along the grove for a couple of inches after which the break line made a slight turn splitting nearly parallel to the line for the rest of the split. It was ugly, but still close enough to the desired size to use (luckily it split in a way that I wound up with extra material instead of missing material.)
