Two points. He's talking about computer grammers, specifically about
the grammer for the Python language. He's not talking about English,
or any other natural language. A computer language is dictated by
the language designer, and if you want a good, flexible language that
can be cleanly extended, you do need to follow some rules about
how you design programming languages.
To stray onto your off-topic response, there has always been some
tension between the prescriptivists and the descriptivists. The basic
difficulty with English grammer (whichever dialect you use) is that it
was invented in the late 19th century in order to have something to
teach grammer school children. They based it on Latin grammer,
and there is no resemblance. The rule about not ending a sentence
with a preposition is typical. I am told that is absolutely true in
Latin. No exceptions. In English, it is perfectly legitimate to do so,
as long as the object occurs earlier in the sentence.
To see why that is the case, you need to consider the actual
semantics of the language. That, however, is so far off topic
that I'm not going to go into it here.

You're quite right it's incorrect. The correct response is
either "Hello?," your name or company affiliation or some such
