Error in Periodic table of the loop macro?

[Jonathan Yip]

In the table, "on" is marked as "same" as "in".

But I tried 

(loop for i in '(1 2 3) do (print i)) 

#| ==> 

1

2

3

NIL

|#

and 

(loop for i on '(1 2 3) do (print i))

#| ==>

(1 2 3)

(2 3)

(1)

NIL

|#

So maybe they are not the same?
