Well there's now a
PolitiFact article on it.
No-one was ordered to leave--nor was anyone forced to be there--and the ones who did leave were primarily the ones validating the outer envelopes and the ones validating the ballots themselves. The ones left were primarily the tabulators, and the ballots were in apparently standard-issue ballot boxes.
Still, leaves a bit of transparency to be desired. For future reference, there should probably be a publicly-announced, easily-accessible, and compiled written record of who enters and leaves, their affiliation, as well when and why they left or entered. Preferably with video recording as well. Observers and poll workers should presumably also be informed with recorded delivery of any sudden changes to the process, such as what Starver mentioned, as well as recorded delivery of their response.
Probably also a good idea to make the ballot boxes more unique so they don't look like suspicious suitcases.
You have people all over the country--and indeed the world--scrutinizing the election. Not everyone is familiar with how the state has set things up. So there's something that could be improved, if only so people aren't left guessing.
