         If present, the <dfn for='VideoConfiguration' dict-member>spatialScalability</dfn>
         member represents the ability to do spatial prediction, that is,
         using frames of a resolution different than the current resolution as
-        dependencies. If absent, spatialScalability will default to
-        <code>false</code>. spatialScalability is closely coupled to
-        {{VideoConfiguration/scalabilityMode}} in the sense that streams encoded
-        with modes using spatial scalability (e.g. "L2T1") can only be decoded
-        if spatialScalability is supported. spatialScalability is only
+        dependencies. If absent, {{VideoConfiguration/spatialScalability}} defaults to
+        <code>false</code>. If {{VideoConfiguration/spatialScalability}} is set to <code>true</code>,
+        the decoder can decode any {{VideoConfiguration/scalabilityMode}} 
+        that the encoder can encode for the configured codec. If {{VideoConfiguration/spatialScalability}}
+        is set to <code>false</code>, the decoder cannot decode spatial scalability
+        modes, but can decode all other {{VideoConfiguration/scalabilityMode}} values
+        that the encoder can encode for the configured codec. {{VideoConfiguration/spatialScalability}} is only
         applicable to {{MediaDecodingConfiguration}} for types {{media-source}},
         {{file}}, and {{MediaDecodingType/webrtc}}.
