So did they compare the total number of steps in the 2 groups? Although the 3x 10 minutes only counted for 3,000 steps, the participants in that group could easily have walked 7,000 steps outside of that 30 minute window.

Also, do people really think walking 10k (or indeed n-k) steps is a substitute for intense exercise?

Considering that between mobile phones, smartwatches and dedicated devices, it is less than trivial to do that, I doubt that is something they overlooked.

This! If you aim for 10k steps the only thing you'd achieve is becoming really good at walking. A good weightlifting session 3x a week is about 100x better for one's health/fitness/conditioning/fat loss/whatever.
