[rules-users] Does evaluating two facts of same type in one when condition works?

[balachandra maddina]

Hi There,

  Im wondering weather the Following rule would work properly,

   rule "abc"

     when

          a : PlaceHolder(value == 1)
          b : PlaceHolder(value == 2)

     then
      System.out.println("print");
.........................
workingmemory.insert(placeholderobject1);
workingmemory.insert(placeholderobject2);
workingmemory.fireAllRules();
..........................................

when i tried, the code is working fine, but How can the rule here is able to
diffirentiate between two facts of same type? any help would be very much
appriciated.

Thank you,
bala.
