You're right. Here's the corresponding shell output:

$ bash
$ ( set -o posix ; set ) | grep -o ^COMP[^=]*
COMP_WORDBREAKS
$ completions '' >/dev/null
[snip]
$ ( set -o posix ; set ) | grep -o ^COMP[^=]*
COMPREPLY
COMP_WORDBREAKS

After adding local COMPREPLY, it prints only

COMP_WORDBREAKS

at the second run. See e7ccc9a.
