In Season 4, Buffy went into the mouth of hell, but in Season 7, she opens the seal and goes into the hellmouth, I know, they're both the same thing, but why is everyone assuming that the Hellmouth is just this one big thing? I mean everyone got a good look in there, it was a huge cavern, probably filled with caves and pits, the whole deal. There's only one Hellmouth in Sunnydale, but who's saying everytime Buffy went down, to the Hellmouth, she's went in EXACTLY the same spot every single time?
