Probably because most of the time for professional software developers aren't spent on fun things such as programming, but on meetings, scheduling milestones, planning resources, even more meetings, and so forth. I enjoy programming both as a job and as a hobby, but there are definitely days where I wrote more code for my side project than for work, despite spending more hours at work.
