Message Prioritization in AE for messages that goes through IE

Dear Experts,

as in PI version 7.1, there is a message prioritization feature for the advance adapter engine. Does this mean that the message prioritization is only for interfaces that does not go through the IE because it is using AAE?

If I create a new rule at the message prioritization for an interface that goes through the IE, will the rule applies to the interface too?

Thank you,
