Not at all.  But you may get such a result if you use a naive regexp, yes.

> This is because of a regexp match in abbrev--before-point which only
> looks back one char.

No, this is because the regexp you have to use must match part of the
text *before* the abbrev.  That's why the doc for define-abbrev-table
gives as example \<\(\w+\)\W* rather than just \(\w+\)\W*.
