That's correct, but only one part.

Eh - not really.  That's some internal magic - to correctly associate
the code with the function names or something like that, I guess.

There is a second syntax to support: a function binding can also have
the syntax (fname EXPR) instead of (fname args body...).  EXPR can be a
lambda expression but also any arbitrary Lisp returning a function
value.
