That doesn't appear to be true.
p { color:red; color:; color:green }
includes a lexical error since "color:;" cannot be parsed as "property
':' S* expr prio?" from:
http://www.w3.org/TR/CSS21/grammar.html#scanner
The validator calls it a "parse error".
If what you were saying were true, the validator would skip to the
matching brace, but instead it reports color: green; as valid CSS
information.

I can see the utility of having no error recovery and I can see the
utility of having the error recovery mandated by the spec. I'm hazy on
the merits of having a second, undocumented form of error recovery that
differs from the spec. It renders the report of "valid CSS information"
deceptive.
