September security update / full Oreo install

[NotFromHere]

I sideloaded the 8.0 update just as soon as the OTA was posted, maybe a week and a half ago now. The "security patch level" was listed as August 5. Tonight I checked updates to see if the September security update was available yet. I received a notification to update to 8.0 with a full 994 megabyte download (or something like that, just under 1 gig). When the update finished, I looked in system info and noticed that it's now showing security patch level as September 5. Why the full reinstall of Oreo? Has anyone else had a similar experience? FWIW I'm using N6p on Verizon.

The new build number that came through for me tonight is OPR6.170623.019. I don't see that build number on the Google OTA download site, which is still showing build number OPR6.170623.013 for the August 5 security patch.

991mb download. Same new build number as yourself.

FWIW I'm using N6p on Verizon.

Seems that Verizon-first exclusivity deal is still going strong in the US. Not exactly a comfort re. the new Pixels.
