You’re correct, but he celebrated it being signed. Directly from the NATCA Press release:
“NATCA's President-elect Rich Santa and Executive Vice President-elect Andrew LeBovidge stated their support of this MOU extension. Rich said, "We believe extending this CBA is a great accomplishment for the covered members and our Union. This MOU will provide stability for the workforce, ensure continued collaboration to modernize the NAS, and provide the traveling public with the safest air transportation system in the world."
Hindsight is 20/20, no doubt. The extension of this CBA through 2026 was a huge mistake by NATCA.
