You don't need to do pulloffs and hammerons the way you do on a real guitar-- just tapping the correct button at the right time is sufficient. For example, if you have a green note and then a red note that you want to hammer, you don't actually need to hold the green down while you hit the red; you can just hit the green, take your whole hand off the guitar, then tap the red and it will work. Pulloffs work the same way, you don't need to mimic the actual pull-off you'd be doing on a real guitar.

True, but it should be remembered that if you have a sequence like GRG, it's easier to do if you keep your finger on green, hammer on the red, then let go of the red (which will act like a pull off.)
