But the only possible way I can interpret the statement "The skill sets
are mutually exclusive." is that knowing one skill set precludes
knowing the other. That is what that statement means.

Sure, that is pretty much the standard definition of "mutually
exclusive", and is essentially equivalent to the definition I gave

And here lies the linguistical problem with your argumentation.
First you state that you cannot have both skills at the same time (this
is what is meant by saying that they are mutually exclusive.)
Then you state that you cannot actually use both skills at the same
time. These two statements are not equivalent.
So what you are trying to say is *not* that the skill sets are mutually
exclusive (even if that is what you actually said), but rather that one
cannot use both skill sets at the same time. These are two quite
(You can know how to drive at the same time as you know how to ski,
thus the skill sets themselves are not mutually exclusive. However you
cannot drive and ski at the same time, so the *usage* of the skills are
Now over to your actual argument.

Writing code to automate a system administration task is programming.
It is also system administration. I do not see that these are

Writing firewall rules is a form of programming, as is configuring some
pieces of software, and even putting together complex commandlines.
These are also all part of system administration. Again I do not see
any clear distinction between the two.
As you can see I disagree with your notion that system administration
and programming are two distinct activities, but rather believe that
many tasks fall into both categories at once.

Maybe, in as much that any erroneous use of language is a communication
problem. (In this case you said one thing while believing that what
you said meant something other than it did.)
