I (BSc) was assisting a PhD student on a project, a project the student was having difficulty with and became very demotivated. Although his supervisor was doing all he could to keep the research going (including bringing me onboard to help), eventually the PhD candidate pulled out. The end result, a paper has been published with my name and his supervisor's name on it, because we ended up finishing the study. So yeah, I can see how his supervisor having yet another paper with his name on it published might seem like the 1%, but reality is, the supervisor had the work ethic to finish off the study and have it published when the student did not.
