It is? It sounds pretty confusing to me... reverse from what?
The right way to specify what happens when composing two transformations
is to just explicitly say which transformation is applied first, instead
of talking about the algebraic operations on the matrix representations.
In my opinion.

See, that makes inherent assumptions about row vs column vectors that
aren't stated anywhere, right?
