Hmm. Have you checked the OpenType specification how the IUP
instruction works?
https://learn.microsoft.com/en-us/typography/opentype/spec/tt_instructions#interpolate-untouched-points-through-the-outline
Have you 'touched' the points you move (i.e., setting
`AF_FLAG_TOUCH_Y`) so that `af_glyph_hints_align_weak_points` doesn't
move them again?
