I can't see the 'sequence below' you refer to but from what you describe you can do this creating a few copied layers of your text.
One layer with the Text filled
A second layer with above that as a Track Matte.
A third layer below that with just the Stroke (outline)
As you move the the original layer with your fill up and down the Track Matte masks it to reveal the outline below.
Let me know if you need more details.
