Because:

1. It was written before their downfall which is around the Great War of Chaos period. Its not the first time something is written like this in Warhammer.

2. It likely contradicts itself again because GW is GW for exampple Kraka Drak:

Canon conflict
Both the Great War Against Chaos and the Battle of Icicle Pass took place in 2302 IC. It appears unlikely that Kraka Drak managed to send an army to help save Kislev and then go on to reestablish ties with the rest of the Karaz Ankor[4a] [4b]  while being under a decades-long underground siege by Valmir Aesling.[2a] [3a]  This could be a mistake by Games Workshop.

And if you search further under Kraka Dorden:

After the complete destruction of the fortress City Kraka Drak during the War in the Mountains (2302-2390) it is likely that Kraka Dorden became the new capital of the Norse Dwarfs.

So its likely or rather left vague if they are truly destroyed, GW does that all the time to ensure they can be still playable as a player choice, but if we go with those examples then the Norse Dwarfs are still alive.
