This is invalid syntax. It needs to be $#{$hoa{key}}

No. $# gives you the index of the last element in the array that follows.

Because the array referenced by $hoa{key} contains 3 elements, numbered 0,
1, and 2. The last element's index is 2.
If you want to retrieve the element at index 2 you need:
${$hoa{key}}[2]
or, the simpler
$hoa{key}->[2]
which can be further simplified to
$hoa{key}[2]
