Thanks Birkir, I think I've understood the difference now:
1.3.1: Don't discriminate and give Your headings the semantic, which they
visually imply.
2.4.10: Make Your content more usable by structuring it with headings.

Betreff: Re: [WebAIM] Heading Structure - Must vs. Nice to habe

WCAG 1.3.1 basically says that if information is available visually it
also needs to be able semantically.
So if something looks like a heading, it should be identified as a
heading (either using the appropriate HtML heading element or ARIA).
Also, if one heading appears to be bigger than another heading, that
needs to be communicated programmatically, e.g. by giving it lower
level, and h2 heading should appear bigger than an h3 heading.
So those are the minimum heading requiremens as I interpret them.
If all headings on the page appear the same size, using the same
heading element for all meets WCAG 1.3.1 even if the content is
structured. WE are giving the same info to all users, even when that
info is wrong.
Of course oth heading structure and heading appearance should
describe the content, but that becomes a usability problem.
