modReLU seems to just increase the magnitude of the input value, and rotate it to the original polar angle. With clipping off negative magnitudes.

Or equivalently rotates a (real) bias term with the input angle and adds that into the original.

  (abs(z) + c)*exp(i*arg(z)) = abs(z)*exp(i*arg(z)) + c*exp(i*arg(z)) = z + c*exp(i*arg(z))
