Recently Kuzenko and McCarty observed the cancellation of 4-derivative terms in the D=4 N=1 Volkov-Akulov supersymmetric action for the fermionic Nambu-Goldstone field. Here is presented a simple algebraic proof of the cancellation based on using the Majorana bispinors and Fierz identities. The cancellation shows a difference between the Volkov-Akulov action and the effective superfield action recently studied by Komargodski and Seiberg and containing one 4-derivative term. We find out that the cancellation effect takes place in coupling of the Nambu-Goldstone fermion with the Dirac field. Equivalence between the Komargodski-Seiberg (KS) and the Volkov-Akulov (VA) Lagrangians is proved up to the first order in the interaction constant of the Nambu-Goldstone (NG) fermions.
