Just because we are calling them in this way. Their operation is very
different from the operation of a classical Tesla coil. The essential
difference is that in a Tesla coil all the energy is present in the
system from the start, and the operation is governed by the zero-input
response of the network. In SSTCs, the initial energy is zero, and the
operation is due to the zero-state response of the network.

Technically they would be "double resonance networks operating with
zero-state response".
These structures with two coils and two transformers are the true
zero-state response equivalent of the conventional Tesla coil.
Versions with direct drive of the primary transformer are essentially
second-order circuits, much simpler and limited in operation
possibilities.
