I've always done it the way showed in the video, but for a reason not mentioned yet. When you cut one of the mosaic tiles in half, you'll lose around 1/8" from the middle. If I just cut a sheet in half, then the off-cuts are garbage. But by running full individual pieces through the saw, the off-cuts will fit nicely in the gap left by the full tiles, because they've already lost the equivalent of a joint line in height from the material removed by the saw.
Also, the time involved is a factor. It takes a lot more time to cut each individual sheet, wipe it, dry it, and then install it, than it does to set up your guide and slam through a couple dozen individual pieces culled from a single sheet or two.
As for it being an easy way to keep it level..."level" is just a matter of perception. No point in keeping a back splash perfectly level if the counter AND the uppers are both 1" out of level over 12', right?
