Not the reason! Computer science is to do with what computers are;
computing science is to do with how they are used. That's like the difference
between being interested in making cars and driving them. You wouldn't expect
a racing driver to be expert in the design of his car [though he may be], nor
a mechanic to be a fast driver [ditto]. In the early years, CS was to be found
typically either as a sub-department of Electrical Engineering or of Applied
Mathematics; that is what drove the separation. Computability is a branch of
applied maths [even if also discussed in a CS dept or in a Pure maths dept],
and it's unsurprising that it's separate from the engineering-like topics of
comput/er/ science but not from the maths-like topics of comput/ing/ science.
People can, and often do, disguise the difference by using CS for both.

A few mathematicians are like that. Most of us are also concerned with
how hard it is to do things. No-one spent a life-time publishing log tables or
calculating digits of pi without also doing whatever they could to improve the
efficiency of the calculation. Numerical analysis has that as a major part of
the discipline, but applied mathematicians in general, statisticians, game
theorists and other sorts of mathematician are more interested in doing things
efficiently than in [mere] theoretical possibility.
[Of course there are many overlaps between different parts of maths,
CS, engineering and other disciplines.]
