DOC - mention of 6 states while there are only 4

[RyanFarrah67]

In the README.md, this is mentionned :

$config = array(
    'graph'         => 'myGraphA', // Name of the current graph - there can be many of them attached to the same object
    'property_path' => 'stateA',  // Property path of the object actually holding the state
    'states'        => array(
        'checkout',
        'pending',
        'confirmed',
        'cancelled'
    ),
    [...]

followed by this explanation :

So, in the previous example, the graph has 6 possible states, and those can be achieved by applying some transitions to the object. [...]

But from what I read, there are only 4 states present in the declared graph and not 6 like said above.
