I think the issue here is more that he probably didn't know how to start a new instance from the taskbar in Win7 - which is understandable as it's not exactly obvious - and was used to doing it from the start menu. However, you could make a case that switching to an existing instance is the more mainstream expected behavior and starting a new instance is a bit more advanced, so it's ok for it to be tucked away a bit more (but convenient enough once you know how).
