Correct, and btw. the ground cable in the main sockets are always a
little bit longer. However, for e.g. the Brauner VM-1 tube microphone
it's similar done as described here:

The microphone is sold to all western nations, used by many experienced
engineers. IIRC we only used a capacitor, however, we bought a capacitor
that is intended for this usage. The switch to chose between a direct
connection and the connection by capacitor was labeled "ground lift".
You might call it hard-grounded and soft-grounded, all terms are
equivocal.
