It may be that a monk has committed two offenses entailing suspension, both concealed for two months. He remembers one, but not the other. He asks the Sangha for probation for two months for the offense he remembers, which he gets. While on probation, he remembers the other offense too. He considers all this and thinks, ‘Let me ask the Sangha for probation for two months for the other offense too.’ He asks and gets it. Starting right there, that monk must stay on probation for two months.
