Are you sure about that?
Did you ask Khaled or are you just taking a stab at it?
Everyone I've asked about it seemed more confused by it's existence & uselessness... (Most assumed it was to tell the height difference between tall and short characters)
Also it teaches bad scripting habits... mirc has to parse useless identifiers and variables when people assume they have to use their full text there.
And there are many identifiers that are similar to each other that omit useless parameters of their counterparts (presumably for this reason) [See token identifiers].
