Grain of course plays a part is how the reaction takes place, but as you
said "but mostly wood cups and checks parallel to the grain and to the
drier side".

As my previous post metnions - never seen a floor/table/deck cup down.

But I don't want to argue it. As said - I am simply repeating it from
information I have read. I doubt anyone knows for sure the real reasons
for it all.

You don't want to argue because you were mistaken, charitably, either in
your wording, or your understanding.

And you are very mistaken in your contention that you "doubt anyone
knows for sure" ... a first semester, college level, Botany 101 class
would prove to you that this is well understood, and well documented
with empirical evidence.

For your future benefit, and so this ends on an instructive note, you
will certainly want to explore the definitive work on the matter:

Every woodworker can learn something from reading Hoadley, guaranteed.
