    When you installed the second drive, there were two resyncs needed.

     

    The first one is to resync with the 4 TB volume.

     

    After that there is vertical expansion to the 8 TB volume.  A new 4-TB "upper" RAID-1 layer is created on both disks, and that also needs to be synced.

     

    I suspect the vertical expansion is what you saw.
