In this note, we explore scenarios in which the concepts of generalized reverse derivation, multiplicative generalized reverse derivation, and multiplicative (generalized) reverse derivation lose significance. First, we extend a result of [Aboubakr A., Gonz\'{a}lez S., Generalized reverse derivations on semiprime rings. {\em Siberian Math. J.} {\bf 56} (2015), no. 2, 199–205]. Then, we demonstrate that in some previous studies, the assumptions imposed on these mappings to establish commutativity (or closely related) theorems are, in fact, unnecessary. Additionally, we provide insights into reverse
-derivations, where
denotes the involution.
