I would interpret these charts as RAT5 did, hold 5000' until 14 DME before selecting a lower altitude of 4000' until 12 DME inbound on 013, then selecting 3400', etc...
However to FLY the approach I would use CDA technique, maintaining 5000' until G/S intercept once LCO established. Code the FMC with ABOVE altitudes to facilitate this and MONITOR the aircraft performance.
Simple
