Also, it says "different directions", but the provided example doesn't
actually *show* different directions (i.e. mixing less-operators with
greater-operators). The provided example "a < b = c <= d" does allow you
to infer relationships between all participants: a < b, a < c, a < d, b
= c, b <= d, c <= d.
