I found this in the users manual:
Swipe and hold
To turn multiple pages continuously, swipe and hold your finger on the screen. Release your finger to stop.
I would suggest all those who have problems with multiple pages turning (using the swip method) make sure they aren't leaving their finger on the page just a bit too long.
Personally, I barely touch the page, in fact I've had the page turn when I just get my finger close, seeing as the IR detectors rest above the screen. One LIGHT brush is all that my reader needs. I've never had the multiple page turns on it (keeping my fingers crossed)
