Exactly - and the same is true with regard to special vs. general relativity. Special relativity is another special case of general relativity for inertial reference frames. And special relativity itself is a necessary consequence of the theory of electrodynamics that Maxwell described holding true in every reference frame. But it no more replaces Maxwell's theory than brings it to its necessary conclusion. And even in the quantum world - which physicists famously can't reconcile with observations of general relativity - Maxwell's equations are true even though we have quantum electrodynamics - which include Maxwell's equations as their foundation.
So the paradigm shifts aren't often as earth-shattering as they seem to outsiders or as Kuhn makes them out to be, because they often subsume and contain the prior theory. The way Morris characterizes Kuhn makes it seem like the different worlds of theory, before- and after- revolution, are orthogonal to each other - or can't even talk to each other at all, because they are using the same terms to describe totally different concepts. But I don't believe that to be true in the slightest.
That said, I must admit that I haven't read Kuhn so I would have to rely on Morris' interpretation of Kuhn - which seems, ahem, somewhat slanted.
Kuhn is very explicit on that the typical behavior is this kind of subsuming rather than outright replacement. He even points out cases where the new paradigm causes us to lose the ability to say certain things we were capable of in the old one.
