I think the point being made is that the two F/Os may (possibly) have been the product of the 'new' training regime. That is, no exposure to stalling, spinning, and aeros, then after the CPL has been obtained straight onto a fly-by-wire computer-with-wings.
I met so many people like this. Fail the FMC and GPS and they're hopelessly lost. I guess it's inevitable in a high-tech environment.
I often got back from a trip thinking 'I wouldn't want to be with that F/O on a dark night with multiple failures'.
Of course these guys were qualified. It's just that it's a lot easier, these days, to 'qualify'!
