A motor which is forcibly stopped can pull a huge amount of current. Depends on motor type but for old fashioned non-electronic controls can be 20x full speed current. Of course we don't know the motor type or controlling electronics. Anyone?
Also DaveReid's post above about motors stopping if they meet resistance.
I can't see any reason for the 'blips' in nose up trim other than pilot trying it and it not working/ not appearing to work. Why else would you release the switch when it's the one thing you're focussing on, the one thing you know you need?
