I see, or rather hear this mostly on new pianos too. The thing is that while it may not happen as immediately and as dramatically on older pianos where, because of wear and corrosion, the friction is higher at the bridge pins, the string will still creep across the bridge over a period of hours, days, or weeks. That's why it ideally would be better to wait a week after a pitch raise to fine tune. In the real world, with real customers, as Greg pointed out, most of us aren't indulged by our customers to that degree and make do with a pitch raise and tune in one sitting - or too often in one pass.
