      Description of problem:

      The following paragraph is wrong or, at least misleading:
      
      Additionally, if an EgressIP object specifies multiple egress IP addresses, there is no guarantee which of the egress IP addresses might be assigned to a pod. For example, if a pod matches a selector for an EgressIP object with two egress IP addresses, 10.10.20.1 and 10.10.20.2, either might be assigned to the pod.
      
      The reason is that, when a single egressip object specifies multiple egress IPs, each 5-tuple (source port, destination port, source IP, destination IP and IP protocol) is assigned an egress IP, but the sentence gives the impression that each pod sticks to one of the egress IPs, and that's wrong. In fact, other fragments of the document do describe the right behavior, so they contradict this paragraph.
      
      The right sentence should say something like:
      
      Additionally, if an EgressIP object specifies multiple egress IP addresses, there is no guarantee which of the egress IP addresses might be used. For example, if a pod matches a selector for an EgressIP object with two egress IP addresses, 10.10.20.1 and 10.10.20.2, either might be used for each TCP connection or UDP conversation.
