Its a documented feature of the language. From the Reference Manual:

"An assignment statement evaluates the expression list (remember that
this can be a single expression or a comma-separated list, the latter
yielding a tuple) and assigns the single resulting object to each of
the target lists, from left to right."

See: http://docs.python.org/ref/assignment.html
