Note quite. If you look closely at the failed test:

; CHECK-NOT: load

This check that the "load" string does not appear, however "load" being a
substring of "download" makes the test fail in your case.

Obviously the test is wrong (the check should not rely on the full path to
the directory in any way), and a work around is to avoid having the "load"
substring appear anywhere in the path. For example using "dl" instead of
"download" should make this test pass.
