Using a motor control (forward/reverse) to control 2 motors, forward

Can you use a motor controller like the VNH5019, or the VNH2SP30 ( used on Sparkfun's ardumotor shield) to control two motor in just one direction? The 2 motors will have a common ground, and making each leg of the controller HIGH will power that particular motor. Will this hurt the chip, not having the current flowing back through the ground side, as in a normal single motor configuration?

There are 10 kinds of people, those who know binary, and those who don't.

A motor controller is kinda overkill for single direction control, even if it's control of multiple motors. Just use a transistor or FET (depending on power requirements). An h-bridge is only necessary for bi-directional control.
