Two Commands Co-Existing depsite Requires()

[pluto7443]

So, we have a problem with using two commands that both require our IntakeSub subsystem. One is the default command, used for manual control of the intake with a joystick, and the other is a command which should override the default. The manual control works fine, however, when the command is called (by pressing a button), the command starts to run, not interrupting the default command. Both commands use Requires(mIntakeSub) in their constructor - why doesn't the button command interrupt the default?
