Following from this, will it be correct to assume that  the appearance of a
let statement after a for statement be also treated as equally undesirable
and error-prone programming technique in XQuery (because in course of
iteration,  a let statement is then forced to rebind  the same variable name

No, of course not. In this case there is no possible risk of confusion about
which declaration the variable reference is referring to.
