If you look up the docs for how assignment works you will see the explanation that a = b = c is evaluated like a = (b = c). The key is this line from the docs: "The result of a simple assignment expression is the value assigned to the left operand." In this case the result of the (b = c) expression is the value in c which is "John". This then assigns "John" into a.
