It depends on you goal.

If your goal is to build open equivalent of specific promoted build of 
Oracle JDK then
right way to do it is:
    1. use hg pull to get latest 7u repo
    2. ensure you are using same source snapshot as promoted build in 
question:
           hg update -r build-tag
    3. Build (you may need to set JDK_BUILD_NUMBER and other variables 
to ensure build identify itself correctly, see 
jdk/make/common/shared/Defs.gmk)

Things to remember:
    - tags are added once build is ready and promoted (and supposed to 
mark source snapshot used for this build)
    - master workspace is updated multiple times between promoted builds 
(there could be other changes when you pull)

If you are building "tip" revision and tag for build in question is in 
the repo then you are likely close to what official promoted build had
but not necessary identical (and sometimes difference could be significant).
