Anyone else able to unlock their phone with a non registered fingerprint?

Not sure why but I have 2 finger prints set up on my phone and Id say about 3 times now I was able to unlock it with my middle finger, not my index.
Just wondering if anyone else has had this happen.

I have a neighbor who's a tech security expert, and he told me that fingerprint sensors are not necessarily the most secure way to lock your phone. Sensors don't read your entire fingerprint--they look for certain key points. It's possible that by moving a non-registered fingertip enough on a sensor, you might by chance hit all of the key points for one of the registered fingerprints.

Nevermind that if somebody knocks you out (or removes your finger, etc), they can access your phone. You don't have to worry about someone shoulder surfing your password, but it really isn't the most secure method. It's darn convenient though and I love it on my phone.
