While it probably does speed up focusing, I don't think that's the main reason.  How else would you have a sharp view in the LCD or EVF?  You move the camera and glance at the scene.  If the camera didn't refocus a bit, it'd be   blurry some of the time, maybe most of the time, unless it stopped down the aperture and made everything in focus, and then you wouldn't have the framing you need to judge what's in and out of focus if you wanted a wider aperture.  There's really not a better solution, I don't think.

Well, it needs to be considered that what you are describing is actually the behavior of all dSLRs in either OVF or Live-View mode, that is it is usually out-of-focus (and wide open!) until you ask for it to focus (half-press the shutter button or AF-ON) on the given scene you are pointed at.

Whereas the usually-in-focus nature of pre-focusing MILCs can be counted as an advantage over dSLRs (i.e. the behavior of a MILC might be more intuitive to somebody who may understand the central concepts in photography, but do not understand the history and technical kludges that comprise the dSLR), the dSLR focus-only-when-asked-for paradigm does indeed work okay...  when focusing is fast.

It's like a slacker genius who can afford to fall behind, knowing that he can catch up in the blink of an eye... versus the diligent-but-not-particularly-brilliant-Joe who has to be on-the-ball all the time lest he fall behind, which might prove hard-to-recover for him.  So he stays diligent and is always pre-focusing so he isn't ever far from where he needs to be.
