Is it worth skipping this update if the update on term increase was successful?

I found it easier to just do the "double"-update than introducing a boolean. Do you have a preference?

When a replica shard increases its primary term under the mandate of a new primary, it should also update its global checkpoint; this gives us the guarantee that its global checkpoint is at least as high as the new primary and gives a starting point for the primary/replica resync.
