Updates to Respond to Motion Actuation comments

OK, Detlev worked on the 620/621 issue responses and Steve and I met and worked on the response to the other (676) issue.

The issue responses:
620: https://www.w3.org/WAI/GL/wiki/Draft_Responses_to_Dec_WD_Issues#620

621: https://www.w3.org/WAI/GL/wiki/Draft_Responses_to_Dec_WD_Issues#621

676: https://www.w3.org/WAI/GL/wiki/Draft_Responses_to_Dec_WD_Issues#676


Pull request with changes:
https://github.com/w3c/wcag21/pull/681 (changes to the SC. We modified the first bullet and also addressed another issue that was raised about subject/verb agreement)
https://github.com/w3c/wcag21/pull/679 (understanding changes so far)

Thoughts?

Thanks,
