Imagine a tree which contains somewhere an element whose name is X. Let's call that x1. A descendant of x1 is another element with name X. Let's call that x2.Correction - the trees of course cannot have partial overlap (they wouldn't be trees if they were....), though XPath nodesets can have partial overlaps.
Invoking //X of course discovers both x1 and x2. Each has its own tree - it's node and it's subtrees. But the tree of x1 overlaps that of x2 - some members of the tree of x1 are in the tree of x2 (In this case it is a total overlap, for other expressions it could be partial.)
