No, but what might happen in some OT fonts is that the subscript iota inherits the GPOS
mark positioning of other below combining marks in the same category. A font is likely to
have a group of below-centre marks, all of which are positioned using the same anchor
attachment points on base glyphs.

Well yes and no. Pretty much any Greek typography expert will probably tell you that the
adscript is correct following the relevant uppercase Greek vowels in the polytonic system.
One does sometimes see subscript iotas in this context, and they are understood by
readers, but they are not correct according to the canons of quality Greek publishing.
What happens with the ypopegrammeni in smallcaps is interesting...
