Scan up and scan down a Staircase?

Hello!

I scanned my first home yesterday. It went rather well I would say. It was a lot of fun too.

My one question was regarding staircases-

There was a room over the garage that had its own staircase. So I scanned up it, scanned the room and then scanned back down the stairs.

Was that the correct way to do it? I figured I couldn't get away with not scanning the stairs going back down since the alignment wouldn't reach from the third floor to the second. 

Here is the final project too :)
