Here and in the remainder of the series, does this fix a specific
issue? The general model we're following is to setup the correct
binding before calling GL commands using that bind point, and not
restoring any existing binding afterwards. (And note that in terms of
restoring bindings, binding 0 would be arbitrary; it's not
particularly likely to be the previous binding for a given bind
point.)
