I suspect he means they might be tempted into 'overcontrolling' but lacks the
vocabulary or brains to say so.

What I mean is that they simply have no experience flying such an aircraft,
and experience with a tin can will not help to any significant extent.
Indeed, it may only hurt, by giving them the dangerous and incorrect belief
that they can fly anything because they can fly a tin can. They will tend to
try what is familiar (flying by hand), instead of what is necessary (flying
with automation), potentially with tragic results.
