Since it didn't measure them it is pointless classifying it as a test of UBI.
A test for lead is usefully classified as a water quality test, even though you need to test for other compounds as well before you know if the water is safe.
Anyone with a job making more than X amount will be losing more money due to additional taxes than gained from their UBI cheque.
But if UBI was self funded (endowment system) we could fix that problem.
Similar to how a university builds up an endowment via donations, and that endowment funds the day to day operations of the university, we could start a "UBI endowment" and encourage people to leave money to it when they pass. It would pay out very little at first, but over time think (50-100 years) we might accumulate enough wealth in the endowment to provide a healthy basic income.
Income accrues to the owners of capital. Currently, the world's capital is held very unevenly. Over time, humanity as a whole should become the owners and beneficiaries of its capital. Bequests to a UBI endowment could be a fairly apolitical, non-radical, non-disruptive way to slowly make this important transition.

Finland just gave the money to unemployed people, so it just became an unemployment benefit.
