I agree it is an interesting idea, and initially I thought it sounded great... but after seeing your post, the more I think about it, the more that change in picture you mention seems like a bad trade-off. It requires "unlearning" which is an approach that is generally best avoided as far as possible, and is unfavourable compared to one that refines and adds to existing knowledge/understanding - think of how increasingly complex concepts in eg mathematics and science are introduced in school.
Perhaps a better solution to address the "Why?" of this suggestion is to include more direct focus on common mistakes that can result in deadlock in (existing or additional) tutorials: demonstrate the problem and hint how to fix the signaling to avoid it, so that after following the tutorials you will hopefully be less likely to make the same mistakes. But there is a fine line here to making tutorials too prescriptive which I feel goes against the general ethos of the game.
