Is Advisory Technique H80 Sufficient?

Hi All--
I was reviewing a website for 2.4.4 (https://www.w3.org/TR/UNDERSTANDING-WCAG20/navigation-mechanisms-refs.html) and wondered if H80 (advisory technique: H80: Identifying the purpose of a link using link text combined with the preceding heading element) can be considered sufficient for Level A.

I've been a proponent of link phrases being self-contained, and was somewhat dismayed that programmatic determination was introduced in WCAG 2.0. But it seems to me that pressing shift+h is a reasonable way to gain sufficient context for an otherwise generic link (like "more").
Do you agree--and thanks.
Mike
