This is true, and, in this case, "confusion avoided" and "what Python does" coincide. The "double equals doing the right thing" is only confusing if you're both unfamiliar with Python and familiar with language design, which is a very small set of people.
People unfamiliar with programming will assume that "if a == b == c" is only true if all three things are the same, and people familiar with Python will know that that is, indeed, what it means.
Programming languages often have syntax that's acknowledged as a source of confusion and bugs and better avoided. The line is not hard and fast, but I write C++ and there's "C++", and then there's "the C++ subset that you should use" (I probably couldn't write C++ code without tools slapping me for using the wrong parts). Operator precedence is debatable but our tools force the use of parentheses to disambiguate.
