Correct, but if there is any significant loss in the ferrites at the
frequency of interest you probably shouldn't be using that ferrite.

OTOH, if one doesn't dissipate the common-mode energy,
the reactance of the ferrite choke may make common-mode
problems worse by bringing the common-mode circuit
impedance to series resonance, i.e. low impedance.
I personally prefer to dissipate common-mode energy
rather than risk making the mischief worse.
