Help With Code - in_array - Check for two or more items

Luís provided me with some code that works great. I want to change it so it looks for two or more user roles. I need some confirmation that I've made the changes correctly. I'll paste the original code, followed by the modified code:

add_action('admin_head', 'hidepopup');
function hidepopup(){
$user = wp_get_current_user();
if ( in_array( 'contributor', (array) $user->roles ) ) {
echo '<style>
.menu-icon-inc_popup{
display: none;
}
</style>';
}
}

Modified

add_action('admin_head', 'hidepopup');
function hidepopup(){
$user = wp_get_current_user();
if ( in_array( 'contributor' || 'contributor-modified', (array) $user->roles ) ) {
echo '<style>
.menu-icon-inc_popup{
display: none;
}
</style>';
}
}

Does line 4 look correct (i.e. || 'contributor-modified')?

Thanks for your help
