It's my belief that ISS sits in a decaying orbit on purpose so other debris is limited. They constantly have to keep pushing up their orbit to stay in space and not fall back to earth.

I jokingly describe the launch of a satellite from the ISS as the crew opening a window and tossing the satellite out. But, in fact, there is a very carefully planned direction to which the crew "toss" the satellites. I believe it's to the rear and below of the ISS, such that when the orbits cross in the future there is no danger that the two will collide.
If, for example, they were to push the satellites to the side of the ISS, then an orbit later the two would meet again as the satellite's orbit would be oscillating to one side and then the other of the ISS. Going to the rear, making the satellite's orbital velocity slightly slower than the ISS, would put the satellite in a lower orbit. But that lower orbit makes the satellite complete its trip around the Earth faster than the ISS, so should put it ahead of the ISS when they meet again. If launched behind and below, then by the time it gets around to the ISS again, it should be far enough away that there would be no possible danger of a collision.
Or, something like that. I forget the details, but it's been discussed here a while ago.
