In both cases, beg (match-beginning index) is the same (at
"write_abbrev"), but start (point, or match-beginning 0) is not. When
INDEX-POSITION was beg, index-alist only got the first match, as ensured
by the member test on imenu.el:841. But now that INDEX-POSITION is
start, index-alist gets two entries for the same-named item, albeit at
slightly different positions.
The beg/start dichotomy might also explain why INDEX-POSITION
occasionally gets me to a rather strange place: `java-mode', for
example, seems to prefer a position two characters before the end of the
keyword preceding the listed identifier - something like "vo-!-id" or
"Stri-!-ng". If there's no such keyword the first suitable character
string is used and I might find myself in a preceding comment.
`cperl-mode', on the other hand, puts me at the _end_ of the identifier
listed by imenu.
