the difference is that in case a thing which is either outer or inner
member of a boundary or multipolygon changes, you will not know whether the
MP has to change or you have to duplicate the old border for the
multipolygon because it should remain. In a site relation it is clearer
that the modification of a member should likely have immediate effect on
the relation as well.

different semantics. IMHO there are situations where explicit relation is
preferable over implicit spatial relation.
This said, I am hardly ever using site relations ;-)
