No, it's not clear I guess :) 'duplicate' does mean 'duplicate me'. If duplicate is set to 0, then you tell the engine not to duplicate the string, but use it as-is. If it's set to 1, then you tell the engine to duplicate it, because this string is either static, or already referenced by other things in PHP.
