Just to cover all the bases:
Is it possible that one of the approaches is in fact a LOC/DME approach - i.e. a Localiser / DME? The two charts would have different radials outbound from the same NDB beacon for the Base Turn, but the LOC/DME would then involve turning to track the Localiser inbound, rather than tracking the NDB.
A Locator / DME approach would (I think) be written Lctr / DME.
I only mention this because I, too, have never seen two different approach charts for the same NDB beacon (so far as I recall). I gather from your post you are quite experienced, but we can all make a mistake reading a chart, particularly if you were just flicking through the JEPP book and glanced at these particular approaches in passing.
If not, then you might be about to give me both barrels for being patronising, which is certainly not my intention. However, I have found that, sometimes, it is the simplest errors of perception that are the hardest to spot and correct!
