L298 driver spec says disable during power up and power down

In the ST data sheet for the L298 dual full bridge driver on page

Turn-On andTurn-Off : Beforeto Turn-ONthe Sup- plyVoltageand beforeto TurnitOFF, theEnablein- put must be driven to the Low state.

Note: Low disables the outputs.

Is there some reason that I'm missing that makes this necessary, beyond perhaps not wanting to have the outputs momentarily yanking around?

I've tried reading the entire data sheet carefully to see if I can spot any reason for this requirement and I just don't see it.

Satisfying this constraint for power up isn't a problem but being ready for power off is a lot less convenient with what I'm doing. I'm driving a permanent magnet motor with this part.

Thanks
