So this seems to work for a very small subset of the words I typed. Also, it seems to only check against dictionary meaning and not cultural usage.
"Tatsu" means "to stand" in Japanese, but is culturally used for erection. This is just an example, I tried a bunch which I know and none were flagged.
Flagging that would be kind of like flagging "hard" in English. Could it potentially be offensive in the wrong context? Yes. Are there brands where that would be absolutely fine? Yes.
That box doesn't seem to permit adding cultural referents / context. If we added all normal words that can have another meaning, it'd flag almost everything.
