@huiran0826, does this look okay? Thanks!

[jboxman]

@alexanderConstantinescu, I've tried to clarify how selectors work in this PR. What do you think? Thanks!

@alexanderConstantinescu, I've updated the comment; I think it is still correct, but it's been awhile since I've written about this, so it's possible it isn't. Can you confirm? Thanks!

@alexanderConstantinescu, although in the diagram, only pods from namespace 1 actually egress. namespace 2 is not selected in the diagram. So that's why it was in its original form, I realize now. I'll have to consider what to do next.

[jboxman]

@huiran0826 can you verify this? Thanks!
