Yes, this is expected. It's too expensive to be constantly updating all of the backup block group descriptors every time we allocate or deallocate a block or inode. What is important to be kept in the backup block group descriptors is where to find the inode table and allocation bitmaps. E2fsck can reconstruct the information which is not updated in the backup block group descriptors and backup superblock, and that's what you are seeing which is different.
