there is no real logic in that. one original word can well evolve into
several separate things - of various forms and meanings, according to sound
alternation rules which were working at a certain time.
just because it did evolve into one thing, this is no reason that it did not
evolve into another thing as well.
concerning the gothic, you have not replied to our earlier remarks that it
is derived via ablaut from bindan.
concerning the form as well as the content of the word i see no necessarity
that "bóndi" should mean someone who is "bound".
