We show that this condition on $A$ implies something much stronger: that an unknown vector $x$ can be recovered from measurements $y = T A x$, when the unknown $T$ belongs to an arbitrary set of invertible, diagonalizable linear transformations $\\mathcal{T}$. The set $\\mathcal{T}$ can be finite or countably infinite.
