NF: 3-5-10-c carries this concept directly to the issue of bleeding and blood on the person or uniform.

If a player takes himself out of action, without the intervention of a game official, he is NOT covered by these rules. If his team elects to call a charged TO to attend to this player, he may participate in the next play. If the apparent injury situation is "discovered by an official" the player MAY NOT participate in the following play, unless there is a halftime or overtime intermission. His team CANNOT buy him back into the game, without missing, "at least one down" with a TO.

I am reading all the rule. You are not. Your interpretation stops at discovered by the official and ignores the timing aspects that accompany the rule.
"C" only makes the bleeding player be considered as injured as under "A".
