ROLE1 +---------> ROLE2

When I call ROLE6 
I assert that ROLE1 and 2 will be executed only 1 time
I get is ROLE1-2 executed for ROLE3 and also executed
Also reexecuted for ROLE4-5-6

ROLE1 META Dependencies : Empty
ROLE2 META Dependencies : Empty
ROLE3 META Dependencies : ROLE1, ROLE2
ROLE4 META Dependencies : ROLE1, ROLE2
ROLE5 META Dependencies : ROLE4
ROLE6 META Dependencies : ROLE5

I'm only calling ROLE6 via

  include_role:
    name: ROLE6 (I know role have to be only lower case ;) ) Its an example.
