How is that not boosting AI? It's certainly not denigrating it

Can't speak for the former, but the latter question: yes.

"Product is really good at X, much better than at Y" does not imply that it's bad at Y, and even if it did, if you're targeting an audience that only cares about X, who gives a shit about Y? Might as well throw Y under the bus to boost the perceived effectiveness of product at X even more in comparison.
