Basically. Put out 10 headlines of job growth to set expectations -> market behaviour. Last part important because you can keep economy humming for some time via perception management and collective delusion. Which affects voter sentiment during election season. Have media that favours you, which MSM does dems, not emphasis revisions in news cycle. It's not about fearing getting caugh because BLS is "transparent", transparency matters much less when you have influence/control over setting news agenda.

That said, were consistent downward revisions last year historically anomolous? I've seen conspiracize so, charts et all. If true, then there's charitably some new artefact in system or uncharitably deception.
