I think this is a tradition in academia, but is not confined there. You can also see it in family newsletters, group status updates, and so on. Someone may write "Dave has completed the new report design, Jill has authorized the new release dates, and Steven is 90% complete on the website updates" even if one of those three people is actually the author of the sentence. Typically it's used where the information is supposed to be coming from everyone and using
me would over-emphasize one person in the group. (In the traditional family brag newsletter, it also lets some people feel a little more comfortable than writing "I won another award for my peach pie".)
It would be pretty strange in spoken English or in a non-academic document with a single author, like an email status report that covers only your own work, or a letter to a friend.
