Just because the Nords know it better does not mean they completely have the upperhand. Since the Dominion now knows what the geography and weather of Skyrim is like they can send in their troops better prepard (Eg. with suitable clothing for cold weather, with enough supplies to last them if they get stranded ect.) and even if the Nords know the overall landscape better if the Dominion knows even the basic layout of it then that lessens the advantage greatly as compared to if they knew nothing about it at all.

Also while everyone knows that a Dominion attack is coming they have no idea whatsoever when it will happen and if the Dominion were to attack soon after a Stormcloak victory then they would still be very capable of causing a very signifigant amount of damage before anyone could do any major damage to them. Now granted they might be able to eventually push them back but if they did the victory would be a Phyrric one or a near Phyrric one.
