This is not a "guide" to anything
This is probably the worst "guide" I've ever read for the amount of work that went into creating it. It's not informative, it's not useful, it's not amusing or entertaining, it just has pretty formating.
This guide would be 10x more relevant if Olimar could say perform a move just before a pluck to choose the Pikmin he wants:
- Neutral A -> Red
- Tilt A -> Yellow
- Smash A -> Purple
- Air A -> Blue
- Taunt -> White
...but that's not the case. Plucking is random.
I feel the need to illustrate just how useless this guide is. Memorizing your Pikmin order and performing moves based on them is not too different from this grandmaster Tetris vid, which shows the next 3 random pieces:

This Pikmin Line guide is about as useful as the shown Tetris player writing a guide to survive the "Invisible Tetris" round he endures while the credits roll. It's a guide that's useful to maybe him (in that it helps him to get his thoughts down on paper) and the one other person in the world that plays the game as his life accomplishment.
If you truly play Olimar to the point that you've become bored with every frame of every possible move in the game versus every other possible move at every pixel on every stage...then yes, burying your brain into the meticulous details of Pikmin randomizations is probably next on your list of things to "figure out" and master about Olimar.
Frankly, most people stop playing the game or die before that time.
A better "guide" would be how to use Pikmin combos. I don't know anything about Olimar (even after reading your guide) but pretending I did, I expected to read something like this:
"If you know your current and next Pikmin are Blue then Purple, approach the opponent from the side with a short hop >B and then Fair."
