Simply put, the scheduling of threads is indeterminate.

The longer answer is that if you want to do this, you'll need to manually wait for each thread to complete its work before you allow another to run. Note that in this fashion, all the threads will still interleave but they won't accomplish any work until you give the go-ahead. Have a look at the synchronize reserved word.
