Nicely done Don. So you are going from tail to foot. ....
The best, most flavorful tobacco (the tip of the leaf) should be placed forward toward the foot of the cigar and the lesser quality tobacco should go toward the head (the round part you put in your mouth). As the cigar burns toward the end the last inch or two is part that gets thrown away and contains is the least desirable tobacco. Makes sense.
If you don't roll using the leaf orientation as shown in the video it's not the end of the world. However, it can be the difference of a good cigar vs. a great cigar and it's no more difficult to roll this way so why not do it?
An easy way to remember this is to ..."Put your best foot forward". Which puts the best tobacco in the front 2/3's of the cigar.
The wrapper will get rolled from the foot up to the head. You'll see in the next video the wrapper leaf gets placed with the tip down pointing at the roller. The foot of the cigar (containing all the tips) is placed on the tip of the wrapper leaf and rolled up to the head of the cigar. Again, that portion of leaf that wraps around the head to create the first cap is the lesser desirable part of the leaf.
Cheers!
