No, he's saying the closest star to Sol isn't Alpha Centauri it's Proxima Centauri.
It's pretty confusing though because "Alpha Centauri" is a 3 star system and the individual stars within Alpha Centauri are named Alpha Centauri A, Alpha Centauri B, and Proxima Centauri.

Reply to comment by frenchtoaster in The vast majority of the 150-400 billion stars in the Milky Way haven't been directly detected. Alpha Centauri is the nearest known star to Sol. What is the probability that there are nearer stars that remain undiscovered? by [deleted]
