Yes, but it's certainly possible to multiply frequency.
One example is here:

However, I'm still not sure if this would make any sense,
because it's really the TV signal that is broadcasted that
should be used for sync, not the power supply frequency. Maybe somebody
didn't have a clue back when TV was born?
