The manual is more recent, so would tend to lean that way. The folding videos were done years ago. I will point that out to marketing / engineering.
It is more mixed up than was stated, and a little different. Also there are "new" support videos which our physical purchase materials point to that have further contradictions and I think are most misleading of all. Consider folding style, bagging orientation, and valve terminology:
-The current support page manual
shows i9s being folded in a unique way, sort of like rolling a sleeping bag. The bow is inside and the stern is outside; I had to really magnify the pdf to confirm how it is radically different than the inward taco folds for i12s and i14t on the same manual page. Also the manual shows placing them lengthwise into the bag, which is important at least for i12.
-The support page videos
(outdoors, old?) show all models with the inward taco fold and being placed lengthwise into the bag. The i9 doesn't appear long enough to benefit from usual angling of the bow and stern so the tips don't overlap. BTW like the manuals, these videos use standard although odd valve terminology where you "close" it to fill and "open" to empty. There is a minor variation from the manual where the videos show tacos facing the wheel end of the bag, vs. the "dotted line" manual discussion implies open taco end facing away.
-The NEW video
(with Jacques published May 2015) which my i12s purchase materials urged me to find at hobiecat.com/quickstart contradicted some above stuff. Some users may not get past this video which I think was a bit misleading. For one thing it says to "open" the valves to fill them, which would lead to all the pumped air reversing back out when you pull the pump away (using standard although admittedly counterintuitive terminology).
Also the new video shows him flopping the only boat (i9s) out of the bag SIDEWAYS, and in a taco inward fold, both of which contradict the manual. Specifically for the i9s the bottom line may be it is forgiving to be folded and oriented any old way, but this example may be bad for other viewers. The i12s and maybe i14 has gotta go keel=lengthways into the bag or you may exhibit the bag-busting exasperation that you see in several threads in this forum. It isn't obvious that lengthwise is best when the boat is stiffly new, but it is important to start a habit of letting the softer boat sides relax into the narrow dimension of the bag.
-The folding cartoons inside the bag
itself are another thing to keep the story consistant. I forget what the i12s bag shows exactly, but I think it vaguely agrees with the manual although simplified to the point of being hard to make out.
RECOMMENDATION: Do not nuke the "old" folding videos. They are the only ones that are unambiguously clear on what to do for each model, and if they have mistakes they are minor. They are inspirational in showing that you can put accessories in and on the bag, which can come as a revelation to those who at first had trouble getting the stiff new boat into the bag at all.
