The period of the debris cloud interactions is about equal to the orbital period of Hubble's orbit. If the orbit was a different inclination but otherwise similar and so crossed Hubble's orbit, it would do so at two points and so the period would be half of the orbital period (it would also require extremely unlikely timing to get it to cross Hubble's orbit and actually hit Hubble at the crossing point, but if it did so at one it should do so at both.)

For it to then hit the ISS, at a far different altitude and inclination is even more problematic.
