There is a bit of exaggeration, for example non-explosive actuators that needed to be released for sunshield to deploy have two redundant electric circuits for their deployment but are considered 'single points of failure' as compound part. Propulsion system is also considered SPoF but there is some redundancy built in, like there are two independent sets of thrusters feeded from one fuel tank. Some other parts don't and cannot have redundancy due to design.
