This is true.

lst is a reference to a list that holds references to 1, 2, and 3

i is a reference to every element in the list, one ofter the other.
But this is not a ref to lst any longer, the list gets dereferenced
before getting at its contents, and only references to that are
returned.

You now have i as a reference to 4, during this cycle.
