Hi, yes. The update is done in the background and would prompt a reboot after installation is complete.
Maybe this helps, sounds like the same issue with another ROM.
I don't remember if lineage is still using a custom vendor or other partitions though, so I'd probably just flash lineage to both slots the first flash, and then use OTA.
Edit: Yup just checked the LOS wiki recommends copying partitions for this device so both A/B are same. Check the section titled "preinstall instructions" in this page.
