# Why have a tanh layer, max pooling layer and then another tanh layer

I have been reading a Facebook paper, read here, and am confused about certain features of the architecture. I do not understand why they have a tanh layer, max-pooling layer, and then another tanh layer. I understand what each layer does, but I don't understand why they have this sequence. Wouldn't this output basically give the same as just a max-pooling layer, and a tanh layer?
