There's the difference: You're studying the other part of the time. As someone who has done every combination except for "study part-time", I can tell that there is a big, big difference between "only working part-time" and "studying and working part-time". You are right that if you study and work, there's a lot of context switching, competing requirements, and lack of real downtime. If you just work part-time, you have control over the other time.
