Going by what was reported in Spullla's thread, they made all of their moves (moving up the main stacks and capturing two cities) shortly after the war declaration, with around 4 hours remaining on the timer. The only moves they made after that was to unload those 4 units close to the end of the turn.
(If they had moved everything near the end of the turn, then surely they would have waited until then to declare war as well).
