Moishe Jacobovits asks:
Why would the side of the opening of the kk Matter when going the side of the mix sach If he had to sprinkle in center if parishes anyway?

The Kollel replies:
As well as sprinkling on the paroches he also sprinkled on the mizbeach when he came out of the kk, so in order to know on which side of the mizbeach he sprinkled we also have to know where the opening of the kk was.
