Does MTP Filetransfer Override Phone Lock?

[e30ernest]

I have Face-Unlock activated on my phone and I noticed that connecting it via USB to my PC lets my PC open the phone's drive even with the phone in a locked state. I'm thinking this may be a security/privacy issue should a device get stolen. Is there a way to lock the drive from being accessed when the phone is locked? At least in my Nexus S, I had to unlock the screen and manually activate USB storage to gain access.

Thanks for your replies!

When my phone locked and then I connect to usb I need to unlock my phone before I can access the drive from windows (jb 4.1.1, but same on ICS).
