Yeah I got that feeling as well, but it's not the main reason that is presented in the training.
The main issue is that your words will be taken out of context and used against the company. If you say "we are going to dominate the market" instead of "our product is going to be really well received" that can be used as evidence of anticompetitive behavior. Nevermind the fact that you're an IC and not a lawyer qualified to comment on if you are truly dominating the market.
