The article (even more the previous article) really misses a reference to matrix exponentials [1]. Everything about X(t) = X^t becomes a bit clearer. Also I think using the term transform is a bit loose here. IIRC Matrix exponentials only work with linear transforms that are represented by a square matrix.
