The Wiki is a bit unclear I'd say.
In short, it's the former "Regional" wing (that, if I'm not mistaken, got quite a bit of his staff from former Crossair) of Swiss, that has a different paying/hiring model (Forget the details, but there are quite some significances) - and which they use now to operate their 777 fleet, as the former mid/long haul Airbus crew would need new certifications anyway. So, by putting their new longhaul wings crew onto (assumed) cheaper contracts, they're trying to cut costs.
