Note there is no $ there, so we might be talking about different things, and this one might be a legacy variable.
This operator just outputs the value of $mln.
I cannot image how this would work if mln was not the current move number.
It works because you are comparing mln with its maximum value. When there are comments, $maxmln will be greater than any move number, but it will be no higher than mln will eventually reach.
