The times I've had a multi-leg flight (internationally), it's always been the same plane. The airline still makes everyone get off, bring in new clean blankets and pillows, and ensure that no one left anything behind. Feels a bit annoying when you just go back to the same seat, but I understand why.

Its a safety thing. No one (except crew) can be onboard the aircraft while its refueling.

I've been on flights between London and Mombasa in Kenya where the aircraft stopped to refuel in Luxor in Egypt and we didn't get off.
