I might be missing something obvious but all three rules are identical
so traffic is going to hit the first rule and go down to user1 chain.


Your user chains don't have any actions associated so looks to me like
it enter the chain, nothing will happen - including not returning to
the input chain so the other rules aren't being hit.
