Blending two images into each other in Adobe Premier Pro 2.0

I was recently looking for an easy way to do a certain effect in Adobe Premiere Pro 2.0. I figured it out, so I'd thought I'd post my solution. Below is the copy of the post on Adobe's forums.

Pasted from Adobe's forum:
I am looking for away to accomplish an effect where I have two images on the screen. One fills the left half, one fills the right half. They blend into each other in the middle. The pictures then each move toward the middle and as they move, they continue to blend into each other. I cannot for the life of me figure out how to accomplish this. I would think you could just take a photoshop document that is half white, half black, blended in the middle, and then apply a luma matte to both images with one of them reversed. The problem with this (and any other type of matte I've tried to make work) is that the matte moves with the image. Any thoughts?

After sleeping on this one I figured out a simple way to do it. Because the image matte moves with any motion keyframes on the image, I put the image in its own sequence, and animated it there. I then placed the image matte on the sequence, and since the sequence has no motion keyframes, the image matte stays put. All that's left is to then put the matte'd sequence on top of the other image that's moving into the center (which doesn't need a soft edge or anything else because the matte'd sequence is on top of it). I've put a sample of what I'm talking about on my blog at:
