Catcher moves up into the batter's box

[TexBlue]

I was talking to a coach who had protested a rule interpretation a few weeks ago. The catcher was moving up into the batter's box, after the batter had moved up to the very front of the box. He felt the catcher had to stay outside the box. The protest was upheld on the grounds that the catcher could not move into the batter's box until the pitch is made.

Look at POE 8 ( for ASA )

....................

(FAST PITCH ONLY)The catcher must remain in the catcher's box until the pitch is released. During a regular pitch to a batter, should the batter be in front of the batter's box, the catcher can move closer to the pate without penalty.

I've always read this as two different situations in the 1st 2 sentences. Does the catcher have to wait for the release of the ball or can she move up with the batter? I have seen posts on this, probably a year or 2 ago on this and I thought then that the consensus was the catcher could move up.
