Consider this conversation:
John: I am giving free chess lessons.
Mary: Nice! You’re a true teacher.
John: How so?
Mary: A true teacher imparts knowledge without a price tag.
John: But what if teaching is his only source of income? Would he not be a “true” teacher then?
Mark (in response to the question above): You clearly mentioned “free chess lesson”.
I don’t see how Mark’s comment adds anything to the discussion or makes sense in the current discussion. It is “redundant” — that’s one word for it — but is there a more fitting word?

The best I can think of is "non sequitur," which means a conclusion or statement that does not logically follow from the previous argument or statement.
Also, maybe it is a boondoggle (Work or activity that is wasteful or pointless but gives the appearance of having value).
Otherwise, it is picayune (worthless, petty).
I'd go with non sequitur.
