Direction Lock: Sammy's new lock screen security

[Ollie]

Samsung has added another way to secure your lock screen. They are calling it Direction Lock and it works by setting up four to eight directional swipes to unlock your S6 or S6 Edge.

Apparently there is a bit of lag from the time you have entered your last swipe until the time that the screen actually unlocks. Reports are claiming up to 2 seconds which seems a bit much considering how awesomely quick it is to just use the updated fingerprint scanner.

Does anyone see a plausible scenario for this?
