Even without setFocus and agenda-group there can't be a loop, for two reasons.
There is nothing here to reactivate either loop, and the Person fact is retracted.

Thanks for for the clarification.

I am thinking to use agenda group instead. At least it would let me activate
Rule 2 from Rule 1 without passing any parameters. However, I am struggling
to understand the following example. Would it end after printing person name
in rule HelloMr or get in a loop, Because, agenda group work on stacking the
rules.

thanks
--------------------------------
rule "MrFlow"
     when
          person : Person ( gender == 'M');
     then
          System.out.println("Mr flow activated");
          drools.setFocus("MrGroup");
end



rule "HelloMr"
     agenda-group "MrGroup"
     when
          person : Person ();
     then
          System.out.println("Hello Mr. " + person.getName());
          retract (person);
end
