What is this property to be called?

Wikipedia calls it "$f$ and $g$ commute" for multivariate functions:

The notion of commutation also finds an interesting generalization in the multivariate case; a function $f$ of arity $n$ is said to commute with a function $g$ of arity $m$ if $f$ is a homomorphism preserving $g$, and vice versa i.e.: $${f\big(g(a_{11},\ldots ,a_{1m}),\ldots ,g(a_{n1},\ldots ,a_{nm})\big)=g\big(f(a_{11},\ldots ,a_{n1}),\ldots ,f(a_{1m},\ldots ,a_{nm})\big)} $$

you my find this equation of generalized bisymmetry.
