Yes, it is normal. The ECU keeps the throttle body slightly closed after shutdown. Since it is a 'Fly-by-Wire' system (electric motor actuates the throttle body butterflies). What you hear is that motor whine. I don't remember the time interval. But it does time out after a bit and the whine goes away.

On the early Spyders, it's something like 30-40 minutes... Not sure it's quite so long on the later Spyders tho?!

I wonder if it is some sort of calibration procedure?
