It should not make a difference whether you call document() once and bind its
result to a variable, or call it separately each time where you need it.
Emphasis on "should"...

Even if you call document() more than once, processors are required to
implement it in a way that always returns an identical root node, and thus the
same document, for the given URI. You should not assume that your processor is
conformant, though. I have seen some, uh, variability in this regard.
The way you are doing it is probably safer, even though it shouldn't make
a difference.
