the route map pointed to by "table-map precedence-map" does the precedence
level assignment for BGP routes in the routing table. Without table-map you
have no BGP QoS going on.

What the example is missing is that there are two forms of that command:
"bgp-policy source ip-prec-map" , applied to interfaces directly connected
to the AS that you want to apply the QoS for, and "bgp-policy destination
prec-map", applied to interfaces connected to BGP peers that will be
applying QoS for traffic moving upstream to aforementioned AS.
Clear as mud? That's how I feel about it too.
