Quick whining noise when shutting down car? (Sometimes when unlocking doors)

I know on a lot of cars the fuel pump begins to engage when the doors are unlocked. High performance cars do this more frequently. My brother's M6 and R8 V10 both do this, it's very obvious. I doubt it's a door actuator, they don't make whining noises like that - it's got to be the fuel pump.

I'm sorry but I'm having a hard time believing this. What would be the logic behind having the fuel pump "engage" (whatever that means) every time I hit the unlock button on the door?

Not trying to be an ***, just playing devil's advocate.
