Yes, I'm aware how that optimization works, it was just about the
implementation of marking them.  So far I had *one* reference point,
and a bunch of secondary points that should match in X or Y.
This is different from having N pairs of disjunct points where each
pair should match in X/Y.

So I would prefer an approach where you mark one point in the 'source'
image, and then are able to select as many points as you like in the
other image that are matched against that point....

Hmm, is that what I'm talking about?  But I was using t1 mode for the
procedure above...

Huh, now that's really puzzling.  I had the impression that 'your'
stitching looked better than the official one.  Or stitching a large
pano and scaling that down gives in general a different result from
directly stitching a small one.  I guess I'll play around a bit with
that...
