Yes, you are right, but it really does not hurt anything.  The extra 
instructions are just to make the tests symmetrical.

Many time with my students, I help them debug problems and go back and 
check with those tests.  The location of the test is thus not always in 
the extracted directory.  The deletion is there as a reminder no matter 
where the test is run.
