From OGL 1.0:

> 9. Updating the License: Wizards or its designated Agents may publish updated versions of this License. You may use any authorized version of this License to copy, modify and distribute any Open Game Content originally distributed under any version of this License.

Just because OGL 1.1 exists doesn't mean that OGL 1.0 / clause 9 stops existing. My license to use OGL 1.0 works seems to continue.

See above. Whether "1.0 keeps working" is (as I understand it) the revocability question. If it's revocable, 1.0 does not keep working. If it isn't, it does.
