You are basically correct except for #2, if I understand your statement.  Your follow-up statement is correct (recently heard list trumps filters).  Server-side filters are -additive-.  So you will always have #1 and server-side filters directly upstream from you will only add to #1, not take away.  This is a very common configuration where people want to see all "local" packets both on RF and directly injected into APRS-IS.
