The theory holds true if you drain the oil, change the filter, fill with new oil and start the motor. The theory is that the engine internals still have a coating on them to give some protection while the oil pump primes. Next time you change your oil see how long it takes for oil pressure to rise as compared to when you start the engine in the morning. My oil pressure comes up straight away while after an oil change it takes a few seconds before pressure builds.
