As an analogy for Java programmers, EPUB is like source code and KFX is like compiled bytecode. There is an equivalence, but the compiled code looks nothing like the source code that produced it.
For most e-books there is a fairly straightforward conversion to KFX, which could be reversed without anything essential to reading the book being lost. It would be equivalent to developing a decompiler to turn bytecode back into source code. A difficult, but doable project.
Added: In comparison KF8 is like EPUB repackaged. It is far easier to reverse the process. Even if conversion from KFX becomes available, conversion from KF8 will be superior as long as the format continues to be obtainable.

I think that Kovid's statement is based on early speculation on the exact content of KFX files. There are multiple variations of a the same book produced for different devices, but as far as I can tell there are only three possibilities that only differ in the handling of images: SD gray scale, SD color, and HD color.
Added: Something similar was also introduced for KF8 a while ago, the azw6 HD image container.
