Why does Rashi on 62a say that penei hamizbe'ach means the darom, just as penei ohel mo'ed means mizrach, when on omud beis the Gemara has a whole derivation of penei?
Rashi on 62a writes that wherever the Kevesh is located, that side is called the "Penei." On the next Amud, the Gemara determines where the Kevesh was located.
