That's correct. The Element must be matching, and must be inside the
subtree rooted by the context node.
"Even though the method is invoked on an element, ***selectors are still
evaluated in the context of the entire document***.
This is also correct. Determining whether an Element is matching does
not use the context node in any way (modulo a possible :context selector
in the future).
I don't see a contradiction here.
Note that there have been proposals that the matching algorithm take the
context node into account discussed in the past on this mailing list (or
maybe on public-webapi). I urge you to read those threads.
