DannyMilksI am actually wearing a pair of XL's of this exact same model right now [Chestnut] which is the reason I was drawn to this page.
Also own a pair in Charcoal and Gray, the Gray being a color MD should try and carry in the future.
Not sure the term "cahoots" applies in this case, since nothing nefarious is being attempted, but to answer your question, no, its definitely a coincidence :-)
There IS a chance that the other person also has an IPS panel monitor and that maybe why he noticed this as well.
