Oddity on installation of PB 4

I'd downloaded and began installation of Public Beta 4. At the end of installation it said I'd need to reboot to renew my profile (I assume to verify my being part of the Public Beta program).


So now I reboot and find the update redownloading. Though I see from About this Mac that I'm running build 16A270f. Isn't that Public Beta 4?


Why is App Store redownloading the whole 2 GB update when I already (I think) have the latest beta installed


much obliged
