We are also told that he knows the Final Getsuga Tenshou as he says his Zanpakutō did not easily teach him the technique. He says that in the Dangai Precipice World.

Any theories or does anyone know how he has the same technique as Ichigo?

Actually I believe the answer is quite simple.

It might have everything to do with Ichigo's unique conception.

After all his mother was a quincy that got bitten by a hollow, and a Vasto Lord at that. His father became a shinigami/human hybrid to save Masaki.

Nimaiya himself said that the hollow power sealed inside Masaki, fused with Ichigo's shinigami powers. Most likely due to his unique nature, of being shinigami/hollow/quincy gave Ichigo similar powers to that of his father.

After all hollows are know for consuming other hollows, and even acquiring some of the traits of the hollow they consumed. So most likely the hollow power inside Masaki mimicked some of the traits of Engetsu.

Look at the names. Engetsu and Zangetsu. It screams that one of Ichigo's other aspects absorbed a part of Isshin powers.

This is what I believe.
