The only reason I can think is that at that time there is no way to know if
that wordchar is going to be in the middle of a word or not. If it appears
at a word boundary, is not what ispell.el seems to consider a wordchar.
Did your test work only with CASECHARS instead of CASECHARS+OTHERCHARS?

For the records, I see the same problem in other languages for valid words
including "otherchars". Since I was recently playing with Catalan I tried
with "intel·ligent", just after typing the middledot "intel" is marked as
typo and only when I finish correctly typing word the mark disappear.
