Indeed, it's not only a problem of scope (with setq you modified global
dynamic variables, which is dangerous because it _may_ interfer with
other functions using the same variables.

But your problem was because you modified a literal object originally
built by the [0 0 0 0 0 0 0 0] expression.  But it is always the same
object that is modified every time you call the function.  Hence the use
of vector or make-vector, which create new vectors each time they're
evaluated.
