The issue is the ordering of processing the requests.

So if request A arrived on interface 1 before request B arrived on
interface 2, the trade described in A should be performed before the
one in B.

This is not "arcance" as you seem to suppose it might be, but rather
pretty clear fair handling or requests sent between trading desks.
