Moon in same nakshatra with high Stree Dirgha

Hi all,

From a Vedic relationship compatibility point of view, if moon nakshatra of both man and woman are same, with man' moon behind woman's moon, does that -

a) is there High Stree Dirgha? Kala in some cases is giving low Stree Dirgha value probably because in calculation it is the same nakshatra 

b) is that match favourable? Given there are no other blemishes
