Wow, I got like 4 copies of the same email ;)

The reasons are pretty similar I'd say. One cannot assume that just because
it's internal access only, no one from outside can access the app (think
botnets, CSRF).  Furthermore there're human problems that need to be thought
out and guarded against, either by genuine mistakes/user idiosyncracies, or
by the typical disgruntled employee.

Good example of an "internal only" app still being vulnerable from outside:
