The second point means that you can extend you H-1B beyond 6-year limit if your new company offers you an approved LC (before the current regulation sunset) that makes you eligible for the 7th year extension.
Anyway, in order to extend your H-1B, you need to have a valid LC (approved or still pending) that passed 365 days or to have an approved 140 at the time you need to extend your H-1B.
If you can not manage to achieve any of the above. My advice is, File LC as soon as possible. Take a long vocation (enough time to make pending LC one year) in China. Then come back and extend your H-1B by one-year.
