yes basically that notched key is a holdover from when there was point ignition - that notch fitted down into the breaker box to hold the removable cam lobe (for the points) in place... the notch was there for clearance through the breaker cover gasket.. the longer edge still fits into the crank groove with the shorter edge fitting to the flywheel groove., points or no.
