The "inputs" to H are two pointers.  They have no halt status.  What
H(X,Y) must correctly report on is the halting or otherwise of the
function call X(Y).  Your H does not do the job it is supposed to do.

You are correct that the proof does not apply to your H.  The proof is
about supposed halt deciders D such that D(X,Y) == true if and only if
X(Y) halts and false otherwise.  Your H is not such a function -- you
can make it do what you like.
