Yeah, but that's a really challenging line to draw diachronically.
For example, clip = to fasten originates from Old English `clyppan` (to embrace/clasp/surround), while clip = to cut originates somewhere Scandanavian, as in Old Norse' `klippa` (to clip/shear). Are those still homographs? I think a fair number of the list items are the result of convergent evolution.
Homographs are words that are written identically. I don't understand what you're trying to ask - the etymology of a word is not at all relevant to how it's spelled.
