A bad hold in winding will not keep the starter motor from engaging. The pull in winding and the hold in winding work together to pull the plunger into the solenoid. Once contact has been made between the battery stud and the motor stud the voltage is the same on both ends of the pull in winding so it will no longer act as magnet.
What will happen if the hold in winding is bad is when contact is made and the pull in winding drops out, the spring will push the plunger out which will disengage the contacts so the pull in winding will again pull the plunger back in to engage the contacts. You will hear the starter chattering but if it spins it will not have enough power to crank the engine.
On the other hand, most likely a new solenoid would cure the problems he has.
