"Should"???

How can it do anything else; there's no return leg any longer.

Some power will still flow through the motor. The path is 120V
from the still hot leg, through the motor, through all of the
120V loads (in parallel) on the tripped leg, and thence to the
neutral. The fraction of the 120V that appears across the motor
depends on the ratio of the motor impedance to that of those
paralleled loads. In any event, current through the motor
cannot be higher than the sum of the currents those 120V loads
would normally draw.
