My bet for why they're comparing it to the Intel models: They want to advertise more heavily to the Intel folks so they can more quickly reduce / remove support for multiple architectures. They are trying to convince the Intel folks that Apple Silicon will be much more performant. Also, they probably want people to spend money on their products sooner than they otherwise would have.
That being said, They are still comparing against the M1 chips here. They aren't only comparing against Intel.
