Actually a less ambiguous way to write that (actually the more official type from what I know) would to be to take the very end of the line that makes it ambiguous between lemon and demon and extend that so it crosses over the loop (assuming it is in fact a "D" not an "L") if it was intended to be an L, they shouldn't have brought that line all the way up to the loop, and stopped about halfway
Now, imagine the opposite, you getting a demon when all you wanted were some lemons.
