I just watched this video segment about how to discharge a capacitor for safety.

Can anyone spot a tiny flaw in the demonstrated method?

First of all his manual start procedure is dangerous, as it risks his fingers getting caught in the blades as the motor starts.

Second, a direct short on the capacitor with a screwdriver is not a good idea.  Better to see, with a voltmeter, if there is a charge that needs removal.  If so, a resistor is better than a screwdriver because you might get a big spark, but frankly I have done this without a problem.

Switching it off before sticking your fingers in may not be safe enough; better to disconnect it entirely from the power line/mains.

IanB:
There's something else, that is a bit more fundamental.

The switch mounted to the side of a furnace is the service disconnect as far as code is concerned. It's very typical to just switch it off there when servicing rather than going to the service panel and shutting off the breaker there.
