I am not reading anything into the rule. The rule is simple the call on the field is the judgement of the official who made it. No one else. It his his call to make. He made it. If you think it was wrong that is your opinion. But, once the call is made it is what it is, in this case no one had a better view than the linesman on the field. Thus by rule, the call on the field was correct, and there wasn't enough evidence on the replay video to overturn it.
