what range confine nested sell sql server?

consider following sql:

begin tran
set transaction confine turn review committed

insert bands
    (  name  )
select 'depeche mode'
union
select 'arcade fire'

    -- i've indented middle transaction clearer.

    start tran
    set transaction confine turn review uncommitted

    name *
      bands

    commit

-- confine turn right here?

update bands
   set name = 'modest mouse'
 where name = 'oddest house'

commit

in sum, start transaction set the confine turn read committed. following futile sql start another, nested transaction. transaction change confine turn read uncommitted. following dedicate transaction relapse other.

now, speculation after middle commit, confine turn advantage read committed. correct?
