They are not one in the same, even though it looks like it. Look at the outhouse/portapotty on floor 6, in the corner, you can just catch the top of it. Hard to see the difference between floors 6 and 7 though since floor 7 is stepped back from the floors below.11th floor if you take into account that floor 6 & 7 are one in the same in the above photo.
Walk east/west along Johnson to get a better view of the building and then you'll see the distinction between 6 and 7. So... Floor 10 working on floor 11 :-)
Edit:
Here is a photo from a month ago, with a better view. They were on floor 9 prepping to do floor 10 back on Jan 4th.
