I'm inclined to believe that it is not (outside of UVLS dots and the situation Souxlya described), but it is probably a close call (and if you like to pad the meters, an easy position to take).
That being said, no amount of "testing with a fellow chicken" will be conclusive, as that fails to control for far too many variables. In addition, the way RPPM trinkets work Breath of the Hydra should NOT benefit (or be harmed) from the additional targets.
