Makes sense to me. The only thing I'd change is to use "in a depth
first fasion" instead of "from the top down", "depth first" (v.s.
"breadth first") being the standard idiom when talking about
this tree traversal strategy. It also matches up with some
of the vocabulary (e.g. "deeper") used later in the paragraph.
Er, ok. It could also say "component" instead of "subcomponent",
in the first instance. And "to the full name of each node in the
filesystem's tree" instead of "to each subcomponents full name",
in the second instance. And eliminate "the subcomponents" in the
third instance.
Patch appended. (Which does not perfectly match my comments
above.)

Note that, when using the bf(--recursive) (bf(-r)) option (which is implied by
-bf(-a)), every subcomponent of every path is visited from the top down, so
-include/exclude patterns get applied recursively to each subcomponent's
-full name (e.g. to include "/foo/bar/baz" the subcomponents "/foo" and
+bf(-a)), every component of every pathname is visited
+in a depth-first fashion. In this way
+include/exclude patterns are applied recursively to the full name of each

-The exclude patterns actually short-circuit the directory traversal stage
+The exclude patterns short-circuit the directory traversal stage
when rsync finds the files to send. If a pattern excludes a particular
