Caveat: It still isn't clear to me which order is correct as there is some inconsistency in the way the function is used.

Comment of Maria:

@ZenBowman This is not a bug. The first image is really "query image" (or "source"), the second one is "train" (or "destination"). Descriptors matching is usually asymmetric: for each query/source descriptor it looks for the nearest descriptor among a training/destination set. "matches1to2" means matching from 1st image to 2d image, i.e. 1 is "query", 2 is "train".

Simply said, this bug report can be cancelled since it is not a bug. Both pull requests were closed down also.
