By default, a PJ on the same datum will not apply a LDT, is intended for transformations between datums. However, in some instances you might want to convert between LDTs on the same datum, such as when you have two sets of coordinates that you KNOW came from WGS84 and were placed on this datum using differnt LDT's. If you want to combine such coordinate systems, one or the other should be converted to the other's LDT. Note that a more logical way to do this would be to convert both sets back to their original WGS84 coordinates and combine in WGS84.
