Yes, they move the film into frame position, but then the fine movement
is done by moving the scanner head.

This does probably allow for more accurate scans in multi-pass
situations.
Why would that be?

Using a microswitch or an optical sensor to detect the
zero position is less accurate than the resolution of
most scanners, which makes multi-pass multi-scanning
impractical with these scanners.
I disagree. They don't have to re-home for each pass. Once home as

Somewhat true, but power supplies can still be quite heavy. It is 19.8 lbs.
Not really light, but certainly not all that heavy.
