Simply re-read more closely the text that you have quoted and you will see
the answer.  I have marked the relavant parts using "***" so you can see
what you need to re-read again:

That means PropertySheet() creates its own handles internally.  You will get
different handles than you would have gotten had you called
CreatePropertySheetPage() yourself directly.

The dialog box procedure is *not* the Callback function that was specified
in the PROPERTYSHEET or PROPERTYSHEETHEADER structure.  That is used for a
completely different purpose altogether.  Having an lParam point to a
PROPERTYSHEETPAGE only applies to the specific condition that the *dialog
box procedure*, not the *property page callback*, gets called with the
WM_INITDIALOG message.

As you can see, the WM_INITDIALOG message does not use the original page at
all, but a copy of it instead.  A different pointer, and thus a different
lParam value, is being used.
