That IP address does not appear in the edit history, so it is possibly a user's IP address.
I may have misinterpreted the log output, that these are edits which have been *prevented*, which is why it's not in the edit history. Stay tuned.
At a glance, the database queries do not appear to search for the supplied username in the afl_ip database field. The actions in the linked log appear to be edits that a logged-out user attempted to make but was prevented due to AbuseFilter.
I don't think there's a bug here. It looks to me like the user tried to make the edit logged out, the filter stopped them, and they then logged in and successfully made the edit.
