Maybe it's because the Germanwings engineers are smarter than BA.
Maybe they've noted the risks of working on 2/2 engines on any 1 occasion without extra precautions being taken.
Maybe they've read the accident report to G-OBMM and paid heed to the recommendation regarding simultaneous critical work on both engines not be accomplished on routine basis.
I think the OP was asking why only the outboard cowl departed and not the inboard one on the same engine (given that they are latched to each other), rather than why the other engine wasn't affected.
Any suggestions?
