Non-commutative operations in `foldRight`

[t-rutten]

The behavior of Semigroup.foldRight and Monoid.foldRight is different for non-commutative operations. For monoids, we have:

Lazy<String> resultMonoid = Monoid.monoid(String::concat, "").foldRight("", Arrays.asList("1", "2", "3", "4"));
resultMonoid.value()
// "1234"

For semigroups:

Lazy<String> resultSemigroup = ((Semigroup<String> String::concat)).foldRight("", Arrays.asList("1", "2", "3", "4"));
resultSemigroup.value()
// "4321"

It appears the order of arguments is reversed inside fmap of the semigroup implementation (source). Is there motivation for this difference between foldRight in the two algebras?
