Ohhh, I guess if you think of it in terms of that it makes sense.
I wonder if it's just an oddly worded hint that is parsed wrong by people like me (or maybe just me, idk). Your logic checks out though and is most likely the correct one!
Many times I've run into puzzles that just didn't make sense to me because the developer's intuition or logic flow didn't line up with mine. Sometimes it can help to play other puzzle games by the same developer to try to get a sense for their logic.
