Sounds like these are recommendations some organizations can use or substitute by better methods of auditing. I would argue that if fraud can be covered by the presence of an individual, the problem is with the audit processes and controls in place.

Plus the individual being aware of the requirement could easily circumvent by only stealing every quarter or every month :-)
