Yes, but you're missing that overtaking events is just one of the metrics in question.
You're right that perhaps it is a big difference between cyclists, my guess would be the number of cars matters more than the number of cyclists. The study has been replicated elsewhere.

At the margin, these things make a difference, especially given that collisions are rare as a fraction for rides taken.
