// Task 3 releases the semaphore; previous count: 0.

Should be

The example is not deterministic, which is why the docs state "like the following". Run the example multiple times and you'll very likely get different output each time, including a different value for the previous count on that line. I just ran it several times, and for the Task 3 releases the semaphore; previous count: line, sometimes it's 1, sometimes it's 2, sometimes it's 0.
