I am also studying the same tutorial and I may have an explanation if you 
do not mind the fact that if you are lucky I am as an inexperienced user as 
you are.
Hopefully there will be someone more experienced than us who check my 
answer in case I wrote bullshit.

You may find a similar context for your question at chapter 8 when a 
remember_token is created and the book says that "there’s no way for the 
test to get access to it".
As far as I have understood, the point is in the call of 
'user.remember_token' or, in your case, 'user.reset_token'. In the 
fixtures, user does not have a reset_token: look at the fixtures and you 
will see, there is not a reset_token attribute. It is true that it takes 
that attribute dynamically via the create action of the controller, but 
once you exit from the action, user is back again the user from the 
fixtures, with no reset_token attribute (that's why is defined 'virtual': 
once you exit from the create action of the controller it is lost).
Using 'assigns(:user)' let you have access directly to the user defined in 
the create action and retrieve the token.
Does it make sense?
