Can I say that "unremarkable transverse peculiar velocity" is "vernacularly dissonant"? Is there a better way?

In the Astronomy SE question What does “unremarkable transverse peculiar velocity” mean exactly, and how is it calculated here? I made the following comment:

The peculiar phrase "unremarkable transverse peculiar velocity" is vernacularly dissonant, but parenthetical clarifications in the body of the paper help with that

I feel that in common spoken English when we say something is peculiar it is unusual, and we are making a remark specifically to indicate said peculiarity. So calling something both unremarkable and peculiar within the space of a few words is dissonant.

Of course taken in context, the term peculiar velocity is well defined in galactic astronomy:

In galactic astronomy, peculiar motion refers to the motion of an object (usually a star) relative to a Galactic rest frame.

and in this context it just means that this parameter is unremarkable, it’s not too high or too low for its location.

Question: But was my remark that it is "vernacularly dissonant" correct for what I’d wanted to say, or should I have said "vernacularly contradictory" or something else instead?
