The orbits were in different inclinations. ISS could not have made the plane change.

I know, but inclination changes can be made with thrust.

"I know, but inclination changes can be made with thrust."

As I recall, the deltaV for an inclination change is the sine of the angle times the velocity. To do a 1 deg plane change would take about 450 ft/sec delta-V. The Orbiter was in a 38 deg inclination orbit (I think). ISS is in a 50 something degree orbit. You do the math.
