No, the /Q3 -> /Q2 was done in XXCOPY as like a "kludge"
(although we had a reasoning for doing so, it was not right
and we have received a handful of "negative" feedback on
this questionable behavior). So, I don't think you will find
it documented anywhere. You may feel strange reading this.
But, we make thousands of similar decisions inside XXCOPY
without making a formal announcement or documentations.
In most of those cases, the XXCOPY behavior makes sense to
most users and nobody raises any question. In some cases,
users ask questions and we have a good and persuasive answer
on why XXCOPY behaves in certain way. In this case, our
reasoning is admittedly weak and I now call it a kludge
(nevertheless, it was deliberately done years ago and left
as it was).

I think we have to clean up the way XXCOPY works with /Q3
which requires a user-prompt in the future.
