You're right -- it's only the free "X-pack Basic" code that will now be available under SSPL. But that does mean that all Elasticsearch distributions will now include the former "X-pack Basic" features.
That seems to be what they are suggesting by making the "free" box in the 3rd column span both the "free" and "free/basic" tiers of the previous columns.
Unless they plan to make those modules paid which were previously free, which I doubt
