Yeah, and always faster than whoever else was there. I suspect that Horner's plan is to see how Lawson handles the Red Bull - he has a higher ceiling than Yuki, potentially a Piastri caliber teammate to Max. But if he's not ready for it or the stage is too big for him (sort of like Gasly's break down), then he can easily swap Yuki and Lawson and see what Yuki can do.
Sucks for Yuki not to the get the shot but I think that plan is pretty sensible.
