Don't know the reason, I didn't write that code, I just had to study it while working on FTS3 integration into Perl's DBD::SQLite. I didn't try nor didn't check in detail, but if your tokenizer treats "play-off" as a single word, then probably the query analyzer will receive one single token and will not interpret the hyphen as NOT.
