documentation typo?

[jhnc]

https://amoffat.github.io/supertag/tips_and_tricks.html states:

However, "stat transparency" means that although person-1 isn't the immediate child of photos, we can treat it as if it was. This means that you can do ls people/person-1/⋂ to list the intersection of those two tags, without needing to go through the people tag group.

Should this be: ls photos/person-1/⋂ ?
