Yes backlight strobing is what all these new "motion blur reduction" features like ULMB and ELMB do.
>it just appears to reduce it
It removes the motion blur caused by persistence of vision.
When an object is moving across the screen, the LCD will display it like this
o
o
o
The object position is updated every 16.66ms, but your eye moves finer than that. You will predict where the object should be between frames and track that with your eye, so your eye position actually looks like this:
o*
o *
o *
o *
o
But the problem is that the object is still there as your eye moves to the right. So the object smears across your eye just like if you held out your hand and stared at it while someone further away runs from your left to your right.
Strobed backlights just flash on briefly once per frame. So it looks like this:
o*
*
*

CRTs only have a few lines litten up at any time, which gives the same effect.
So well, there was never any blur in the first place, it just appeared that there was. And strobing undoes that blur effect.
The only real blur is caused by slow pixel response, which can be captured from a still small exposure time camera, unlike the persistence of vision blur described above.
Also interesting is that with strobing backlights, some LCDs are waiting until the pixel transitions are complete and then strobing the backlight, so the pixel response time no longer matters (except maybe the pixels at the bottom of screen). However this introduces lag, but I'm not sure if it's perceptible. I've never tried a strobed backlight LCD since the stores don't have them set up properly.
