There have been many cases of people in finance being able to cover up significant losses of company funds (through bad trades or what not) or a long period of time simply by understanding the front/back office systems.
If you force people to leave (and cut off remote access) they are unable to maintain the pretenses required to cover up these losses, and can help drive exposure of foul play. At a minimum you'd need two people 100% in on the cover-up which reduces the chance of it happening.
