I don't understand this at all.
that sets the two variables to be essentially random strings.
I'm not sure what you mean by points to the same document, do you mean 
content/@src and id(@mapRef) always have the same string value?

So ignoring all that for a bt and going back to the original question,

if $x is an element  node and $y is another element node then 

count($x/*|$y) = count($x/*)

just if $y is a child of $x which is what I think you mean by direct
descendant.

count($x//*|$y) = count($x/*)

if $y is a descendent of $x
