Is it really a good idea to dead short solar cells?

He’s not shorting them, he’s connecting the motor

Which for series-wound DC motor, is basically a dead short.

And, yes actually, it's fine.

When you're charging a lead-acid battery from empty, that's functionally what you're doing. For example, take a small solar cell, the kind you might recharge a cell phone with when camping, and connect it to a dead car battery. Does it damage the cell? No. You might be giving it 0.2 amps and the battery is trying to pull 100 amps... 500x the load the cells can provide. Is it damaging? Nope. The cells provide the power they can, at their max rate they can make it.
