Its not a problem as long as they stay in sync else the gantry starts to twist - although the impact of that depends on the gantry rigidity. Therefore loosing steps on one side is a definite no no.. Usual solutions to this are one drive, belts to two screws or making sure the motors never stall out by oversizing them (using two motors each sized to do the task individually is one approach).
