No-one is missing an irrelevant part of the standard, least of all the people who wrote it.
We know X and its subobjects are not permitted to appear in a variable definition context.
But there is no prohibition, for Y, a local variable, or its subobjects, from appearing in such a context.
If you are going to claim Y%P is already covered by C1594, you have to show how Y%P is
* accessed by use or host association [and it’s not]
* in a common block [and it’s not]
* is a pointer dummy argument [and it’s not]
* is a dummy argument [and it’s not]
* is a coindexed object [and it’s not]
* is storage associated with anything else [and it’s not]
Being pointer associated has nothing to do with any of those things. And “being pointer associated with X” is not “being X”.

I never said that it wasn't pointer associated.
X is available in the subroutine via host association.
That is, it is a host-associated variable.

This is the relevant part of the standard that I think some
