Like Ernest, I was confused by the terminology being used to describe
the problem, until I loaded the Protege project and saw what you are
trying to do. I think the JESS rule you want is (minus the back-slashes
and spaces):
(defrule simple-multi-multi-match
(object (is-a Hello)(OBJECT ?hello) (ResourceID $?b 111 $?a))
?behavior <- (object (is-a NodeSpoof) (Resourcesequence $?before
?hello $?after))
=>
(printout t "Behavior ID: " (slot-get ?behavior BehaviorID) crlf))
In JessTab translation of Protege instances to Jess facts, you have the
Jess template slot OBJECT that references the object corresponding to
the translated fact. That's what you can use in your subsequent matches
for objects.

Q1. what is the logical difference between
(defglobal ?*re* = (nth$ 1 (find-all-instances ((?h Hello)) (member$ 111
(slot-get ?h Resource\ ID)))))
and
(defglobal ?*re* = (nth$ 1 (find-all-instances ((?h Hello)) (eq
(slot-get ?h Resource\ ID) 111))))
Because, the second statement points to the first instance, even if
there is no field matching 111. Just try slot-get after the defglobal in
Jess prompt to confirm.
The second statement should be empty, if your Resource\ ID slot has
cardinality multiple. Thus (slot-get ?h Resource\ ID) is a list, and can
never equal 111. So find-all-instances should return the empty list.
