On the one hand, it is good that she addressed this issue. But on the other hand, as far as I know, there are two possible ways they could have enrolled EC in a health plan if he lost coverage due to a qualifying event. One is to check with her HR department to see if this qualified as a "qualifying event" and then immediately adding EC to her company's health plan. The other is to pay for COBRA health coverage for November and December and then start EC on the health plan coverage with JC's company. COBRA is very expensive though, so maybe they decided just to add EC on to her coverage during Open Enrollment in fall 2021 and his coverage would begin in January of 2022.
In any event, her testimony does provide some context for EC's lack of coverage, and it may have been only for the final two months of 2021 after James C lost his job and thus the loss of EC's coverage.
