I think you misunderstood. At no point did they ever say that the human evacuations were being reversed, or that the situation is not very serious.
They did say that the water levels have declined a bit, such the emergency spillway is not being further eroded, but that is only so until the next big rainstorm or warm day with heavy snowmelt occurs.
The situation is still very concerning and there is not a good medium-term solution in place at all, and the authorities have not said otherwise. So, no, they are not lying.
Thanks!
