You clearly see that it does match, so why do you keep saying it doesn't match in response to my explanation?

1st Pass: It thinks it hasn't matched yet because pos == 0, so it matches, setting pos = 0.
2nd Pass: It thinks it hasn't matched yet because pos == 0, so it matches, setting pos = 0.
3rd Pass: It thinks it hasn't matched yet because pos == 0, so it matches, setting pos = 0.
...

...no repeated matches like in list context.

The while isn't there for decoration. It's the one doing the repeating.
