Trusted devices and places on lollipop - what is the point? ! topic

Okay, so I'm running lollipop on my galaxy S5 and after connecting my bluetooth headphones it asked me if I wanted to add them as trusted?
So, as I trust them, I said yes.
After that, whenever I locked my phone using the fingerprint lock I would instead get a swipe lock screen instead. Swiping it would then take me to my normal fingerprint lock screen.
So, instead of one lockscreen I would have to unlock two!
What the hell is the point of that?
Am I missing something?
