No, it just tells me what the MAIN key is in this Section. I could have named it "Staccato E-D-E-D-D-E" if I would strictly follow the real (and quickly changing) chord sequence. That name would be a violation of clever use, I guess....
There are multiple, alternating, chords in it, and two measures 4/4.
In your example it seems there is no extended solo section necessary, so it doesn't apply.
That's why I'd mentioned the example of CCR's "I heard it through the grapevine". John Fogerty's extended solo is played in D-G a million times as a turnaround.
This is also how my verses (3x4 measures) is built, while my chorus (2x2 measures, 1x3 measures overflow) is the same yet in B.
Also a transposed section in A and even C for additional guitar changes in the solo's.
It's not a masterpiece or rocket science and it will never hit the charts, by all means (), but it's metal as I like it.
