No, array(3) is equal to (in print_r() syntax)

Array (
  [0] => 3
)

and the menu system just uses this standard PHP array as callback argument in 
order to get the real number (and from that, the node itself).
I mean, don't get me wrong - I understand your point, just make sure you 
recognize that this isn't any special node system syntax but standard PHP.
