Yes, that's what Neil was describing, but I'd like to add
one wrinkle. Maybe I'm wrong, but it's my understanding
that the wide staff-spaces are not supposed to be twice as
big, but 1.5 times. So I don't think it's quite the same
dimensions as it would be by Neil's description. I think
the first C is in the position of a traditional F, but the
ledger lines that would normally cut through what used to be
A and C now cut through what used to be G and B.
Incidentally, an almost identical system is credited to
Walter Steffens on p.32 of Gardner Read's "Music Notation".

Would be fun to see this in action.
