The encoder integration order and layers.

[ApplePomme]

The encoder integrates the layers as:

% integrate
lgraph = lgraph2; % residual blocks
lgraph = addLayers(lgraph,layers1); % encoder
lgraph = addLayers(lgraph,layers3); % decoder

It doesn't look like the figure:

Placing the encoder first will not work.
Why's that?
How are the residual layers connected to the encoder and decoder? Thanks.
