Setting $[ does not set a pointer into the array.
Rather, it changes the "names" (loosely speaking) by which you refer to
elements of the array.

the following debug session should illustrate:

  DB<1> @ary=('a', 'b', 'c', 'd', 'e', 'f', 'g');

  DB<2> p $[
0
  DB<3> p $ary[2];
c
  DB<4> $[=4;

  DB<9> p $ary[2];

  DB<10> p $ary[6];
c
  DB<11> q
