It is true that @array can not be undef, but your rewrite I think is

The first "do the comparison only @colored is true" is not about
definedness.  It is "@colored can be an empty array when the user is
not using separate 'show these colored lines to the end user, feed
these noncolored lines to git-apply command' feature, so @colored==0
and @diff > 0 is perfectly fine".
