Why would a BLM meld mind in gear? Does this game do a poor job in explaining stats?

I asked but I did not get a clear answer so I just advised how to remove them. My friend was asking about this in a private ls to another and this was the convo:

This game does an awful job of explaining stats :\
what ya mean? i put my cursor over it and says "affects healing magic spells"
Yeah, but they'd have to actually lok at that to know
it doesn't say "Mind does this" when you pick up BLM

I saw that BLM in wall today in expert roulette before reset, fully upgraded shire, with mind V melds.
