I think it's ex-ante use if valid. The Battle of Marne stopped the Germans surrounding Paris, as they had in 1870 - in that sense it had decisive results.

In contrast, Verdun and the Somme were far less decisive - even though decision was sought.

I have always taken CvCs point to be that you should not seek battle unless you aim to do some serious damage to the enemy, and for that damage to contribute your setting forth of policy.
