Yes, the chapter sub-header has 'recursion' in the name.
But the text says: "If the last expression of a function body is a
function call, a tail recursive call is done."
This in no way can be read as meaning that when the last expression of
a function body is a function call then a tail call is not mandated.
Maybe changing "tail recursive call" to "tail call" would remove an
element of distraction and be more to the point though.
