. . .

I note now that |WA| > |WB| (both WA and WB are negative, and I leave
the proof to the reader). It is difficult to imagine how brick A could
have scraped a longer path over Brick B than vice-versa in any really
meaningful way. . . .

Leigh,
This is not surprising. Since you have specified MA<MB, doesn't A have
to move farther than B to maintain a fixed CM?
