Yes ... "$" is not a digit.  Parameters are not expanded here.

You can get around this with ${(e):-\${DirPath:h$N}}

The documentation for :t is being a bit too literal.  More accurate
would be to say that 0 is always the same as having no digit at all.
In the case of :t counting from right to left :1 is also the same as
no digit at all, but for :h counting from left to right that's not the
case.
