I don't think this reference is as strong as you think it is. Here is
a paragraph somewhat lower:

] If a name is bound in a block, it is a local variable of that block,
] unless declared as nonlocal. If a name is bound at the module level, ] 
it is a global variable. (The variables of the module code block are ] 
local and global.) If a variable is used in a code block but not
] defined there, it is a free variable.

So the language documentation mentions these names as being variables.
