Clarification. Duplicating multiple groups of layers in a "reasoning" loop

Normal:

  L1 -> L2 -> L3 -> L4 -> out

  L1 -> [L2->L3] -> [L2->L3] -> L4 -> out

       --<--loop----
       |           |

  L1 -> [L2->L3] x N --> L4 -> out

Note: ascii rendering HN is not trivial

The commenter "Skerit" below linked to a recent implementation of this:

See the left-hand side of the diagram here, which is your exact proposal:
