eckhard: It"s all the same thing. In the absence of MM, a DME fix is used to define the start of the Missed Approach Segment, so that the turn is not executed too early.
Nothing odd about it. Turn right at 2000' but no sooner than 1 DME. That's what it says. In case of an early G/A, follow the track into the normal place 1 NM short of THR, and only then turn.
I would assume the reason for not allowing the A/C to turn south sooner than 1D is the traffic on downwind.
extricate: Note that the printed MAPt is 0,5D for the LOC. Whereas the start of ILS Missed APCH Proc is defined at 1D. And in the UK they don't call that MAPt either.
