Part-07 confusion

[piperone]

Part 07 tells us the following:

* Run the tests and you will find that the test fails.
* It's time for the REFACTOR stage. Now that we have a
* failing test, we can go and improve our existing code.

And in Part 18, this comment appears:

* Since our tests are GREEN, maybe now is the time
* to enter the REFACTOR stage and try to improve our
* code.

Part 7 suggests the order is Red - Refactor - Green, while other parts tells us it's Red - Green - Refactor. Which is it?

Thanks!

Quiet late for this conversation but leaving a clarification here for others.

The paragraph before that suggests,

 * You know what, though? I'm not all that pleased
 * with our parse method. There's a fair bit of
 * repetition in there.

To make it more clear, the suggested order for TDD is always Red - Refactor - Green - Improve - Green. The last two stages is what the paragraph above is referring to. This is in cases where new functionality is added or improvements are done.
