Usergroup bitfield permissions - conflict issue ?

[cinq]

I need some help trying to figure this out.

I use the following in my includes/init.php for my hack :

PHP Code:

$_BITFIELD['usergroup']['[b]vbarticlespermissions[/b]'] = array(
    'canviewarticles'        => 1,
    'cansubmitarticles'        => 2,
    'cancommentonarticles'        => 4,
    'canratearticles'             => 8,
    'caneditdelowncomments'            => 16
); 


If there are other bitfields further up/down in the init.php file with a similar bitfield name, say 'canviewarticles'

PHP Code:

$_BITFIELD['usergroup']['[b]notvbarticlepermissions[/b]'] = array(
    'canviewarticles'        => 1
); 


There shouldn't be any conflict, since the names of the array is different, right ? ( note the parts in bold in both code segments above )
Or am I mistaken, because it seems it does matter. ( the bitfield name )
Any help would be most appreciated
