Yes.  As far as I can tell, that's *exactly* what the spec is saying.
Is there anything unclear?

Note that you can fall all the way down to criteria 5 if, for example,
one shadow root reaches into a sibling shadow root and then into the
shadow of something else inside of there.  When comparing that
declaration with one from inside the "something else", neither
criteria 2 nor criteria 3 apply, so you end up having to compare
specificity and ordering.
