Game Mechanics: /pet guard here & /pet guard me: different behaviour in early game

[Palemoon]

maybe, I remember my little gnome using his lvl 4 fire pet in the mines of malfunction back when there were more mobs in there and it was like a mini-dungeon.

Actually, this MIGHT of been beta, back when the gnome necro GMs were still behind that false wall in the wiz guild.

But yes, I remember darting into a (crowded with noobs) mines of malfunction and parking a fire pet with /pet guard here and running back out and hoping for the best.
