I found the title a bit misleading. It suggests that USB4 might get a synonym for Thunderbolt 3. But it seems more like the technology will get incorporated to a certain extend into USB4. As long as it hasn't been exactly specified what gets included, it is probably too soon to assume that USB4 will always be compatible with Thunderbolt3.
