Repeating Javier:

  when you have hash slot collisions (8, 16 & 24 all want to go to the
  same slot), only one key can go to the "main" slot, the others go to
  somewhere else.... which could be the main slot for some other key.

This always is possible in closed hash tables, whatever the method
to handle collitions.
