Could it be because academic writing is simpler than the literary one? For example, in math, 'for all yada, there exists bla' is different from 'there exists bla for all yada'. So, you literally memorize these two cliches because they greatly simplify math. There are many other such very precise cliches in math you keep reusing over and over. Even though, it makes your life simpler, to an outsider you come off as an academic bore. That's my theory anyway.
