He said "[...] it is encouraged to think of it that way rather than calling functions." This is what Sandi Metz talks about when she speaks about message/responsibility centric design vs data-centric design in OOP. The conceptual difference is said to lead to different designs. You don't start out your design by thinking about what data you hold but you think about which responsibilities/roles you have and create objects around those by thinking how they might talk to each other to reach their goals.
