Not sure if you are aware, but the Jeppesen version of the AIP is basically cut and pasted from the AIP. The above is the electronic Jepp reference, I don't know the AIP reference, it will be there though.
The position you are putting forward seems to hinge on the concept that the missed approach procedure does not start until the MAP and as the climb is part of the procedure, then the climb doesn't start until the MAP either.
The above paragraph disproves this theory.
The first part of the paragraph states that the procedure
must start at the MAP. The second part allows for situations where the climb has commenced prior to the MAP. It follows then that the phrase "missed approach procedure" refers only to the tracking of the procedure and not the climb. Otherwise an early climb would not be permitted.
