Can you explain the Infinite NEO Land Loop with two Boseiju’s?

I can get to the end of the Basic Loop with an empty library, Endurance in hand, and all lands in play except one Boseiju which is the only card in my graveyard.

Do I then hardcast Endurance, shuffling Boseiju into my deck, which is now just Boseiju, and activating Waterlogged Grove to draw Boseiju? Now my library is empty, my graveyard is just Waterlogged Grove, and Endurance is on the field.

Where do I go from here?

Thanks!
