Closing the LCD viewfinder doesn't turn off live view, does it?

As many of you know the 650D/T4i has a rotating LCD screen and you can rotate it closed so you can't see the screen. I can see that just as it closes the screen switches off - that's good.

The thing is i was experimenting with time lapse shooting so set up the camera on a tripod, adjusted settings, turned off IS & auto focus, etc. but i was using live view to see the output of test images before starting the intervalometer. When i got the setting that i felt was OK i closed the backscreen and started the timer running.

A couple of hours later i came back to find the camera feeling very warm! I wasn't sure why, anyway i adjusted the shutter speed faster as the daylight increased and i realised that the shutter sounded slower than it should and then i had a thought - was it still in 'Live View'?? So i pressed the live-view button and lo-and-behold the familar clack of the mirror[?] dropped down! What!? In my haste it appears that although the LCD viewscreen was off 'live view' was still on - no wonder it was v.warm!

So is that correct, live view stays on even if the LCD backscreen is off? Could overheating/long-term heating cause premature failure of the sensor?
