The magenta line doesn't indicate a boundary between E and G space.
The magenta indicates Class E with a floor of 700 feet. The outside
of this magenta area is Class E with a floor of 1200 feet. A blue
line indicates the border between Class E with a floor of 1200 feet
and Class G. No pure Class G where I am. I can only find that under
the other classes. Note: I am not a CFI and could easily be wrong
about this.

He was talking about magenta circles, which indicates to me that he is
talking about class E airspace that goes to the surface. Either that, or he
is talking about class C airspace. Beyond that, I have a tough time figuring
out what he is talking about. The magenta shaded lines that indicate class E
to 700 feet are rarely circles, although I can think of a few airports in
eastern Washington that are like that. We do have some class G boundaries
around here, particularly over the Olympic Peninsula.

I'm not sure what he meant by circles either, but I took it to mean
the large Class E vignettes that are generally made up of sections of
circles in a sort of unrefined cloudlike shape. I don't know about
the rest of the country, but in the east they're all over the place.
