Probably not. It means that the sulfur oxides are the acid anhydrides of common acids.

Explanation:

So what is an acid anhydride? It is the acid LESS the elements of water, $H_{2} O$ $H_2O$ . The acid anhydride of sulfuric acid $H_{2} S O_{4}$ $H_2SO_4$ is $S O_{3} (g)$ $SO_3(g)$ , the acid anhydride of sulfurous acid, $H_{2} S O_{3}$ $H_2SO_3$ is $S O_{2} (g)$ $SO_2(g)$ . Of course, these are formalisms, but they do help us to rationalize reactivity as an acid-base phenomenon when the sulfur oxides are dissolved in water.
