Actually, the code initializes it on the first call (recursing is
false) and asserts that it must have been already initialized in a
recursive (recursing is true) call.

Okay, sure. Maybe it's better to write the comment inside the if
block, because if recursing is true, we don't drop yet.
Thoughts on suggestion to expand the test case?
