Question on expected behavior when mapping rule parameters while calling sub-interface

#UserInterface
Hi All, I was designing a form where I came across this new or different behavior which I suspect to be a bug. This is related to the mapping of the rule parameters while calling a sub-interface.

I have 2 interfaces, one parent interface(TEST_Interface1) and one sub-interface(TEST_Interface2).
TEST_Interface1 contains two rule inputs : varA (Text) and varB (Text).
TEST_Interface2 contains two rule inputs : varA (Text) and varB (Text).

TEST_Interface2 contains 2 text fields using which I initialize the rule inputs varA and varB.
In TEST_Interface1, I am calling TEST_Interface2 and below goes the code snippet:
rule!TEST_Interface2(
varA: ri!varB,           /* Mapping varA in TEST_Interface2 to varB TEST_Interface1 */
varB: ri!varA                    /* Mapping varB in TEST_Interface2 to varA TEST_Interface1 */
),
          a!textField(          /* Displaying the changed variable value */
label: "Variable A",
labelPosition: "ADJ...
