90 degree inclination all converge over the poles. The dead Russian satellite that collided with an iridium satellite a few years ago is a good example.

Any two circular orbits of equal radius are either identical (potentially excluding direction) or intersects at two points.

which two points is irrelevant to the chance of collision.

To prove the to yourself, tilt the Earth by 30 degrees. Some 90 degree inclination orbits are now 60, some still 90, and the rest in-between. They do not converge over there poles. Did their chance of collisions change?

First, neither satellite had a 90 degree inclination. Second, it doesn't matter if they did. The number of collisions possible wouldn't change.
