I already posted a more complete video that has all this and more.
But let's take a look at the rules again and I'll highlight another pertinent part of this rule here in red yet again since you are reading comprehension-deficient.
RULE 8 FORWARD PASS, BACKWARD PASS, FUMBLE
ARTICLE 3. COMPLETED OR INTERCEPTED PASS. A player who makes a catch may advance the ball. A forward pass is
complete (by the offense) or intercepted (by the defense) in the field of play, at the sideline, or in the end zone if a player, who is
inbounds:
(a) secures control of the ball in his hands or arms prior to the ball touching the ground; and
(b) touches the ground inbounds with both feet or with any part of his body other than his hands; and
(c) after (a) and (b) have been fulfilled, performs any act common to the game (e.g., tuck the ball away, extend it forward, take
an additional step, turn upfield, or avoid or ward off an opponent), or he maintains control of the ball long enough to do so.
So
after Waller gains control AND takes 2 steps, does he
then turn up field? No. In his 2 strides, he is moving in the direction of the offense. Per these very clear rules you cannot turn up field as a football move until AFTER you perform parts (a) and (b) of the rule. Again, if you're already moving in the direction of the offense, you are not "turning" in that same direction. So this is where if you're a ref, you look for a 3rd step unless a defender holds him up and then you make the "control of the ball along enough" determination. "Turning upfield" is not meant for receivers already running forward. It is for situations like I said already where a receiver is facing the QB for a catch (like a standstill leap to make a catch) and turns or is moving parallel and is able to take 2 steps and then turns.
