Pretty much.

Spoiler for Alicization:

The series ended with Kirito getting his brain fixed, Alice was taken out of UW for reasons not yet translated, and him + Asuna left UW after staying in UW for 200 inside-years making sure the place doesn't destroy itself. CotM details a event that happened after the war between Dark Territory and Human Kingdom (WEB 8 plot) ended, when the series have progressed from that.
