Instead the FAA handbook says this
Settling With Power (Vortex Ring State)
Vortex ring state describes an aerodynamic condition in
which a helicopter may be in a vertical descent with 20
percent up to maximum power applied, and little or no climb
performance. The term “settling with power” comes from
the fact that the helicopter keeps settling even though full
engine power is applied.
talk about a wide spread of conditions and the misleading statement that would lead you to believe you have to have full power applied to be in VRS.
