It does not get to. Which of the two imports is refused is whichever arrived
second, which follows the entry file's textual order — reverse the two lines and
the message moves from the package's import to the program's. Both refusals are
correct and the needle matches either, so the test was green while its comment
was wrong.
The comment now says what the case actually tests: that a clash is caught when
its two halves are a directory apart, rather than side by side as in
pkg-two-aliases.
