I'm not really sure about that, it may be that the rubberbands get
mangled into curves in certain projections. And so vertexes from other
polygons might "jump" on the other side of the rubberband.
Indeed, I would assume that too.
Projections do not preserve parallelism, so I guess that the same
geometries projected in two different srids could have different
ST_Relate results.
If you want "true results", I think you have to go for a real coordinate
space like 4326.
Thinking a bit more about it, maybe those spatial relation checks are
always internally performed in unprojected coordinates.
That would be logical, since projections are just a representation of
real things, relations should be checked on the real things rather than
on their representations.
