What is the ruling if a person emancipates two slaves for two expiations collectively, stating, 'I freed these two for the two expiations,' without assigning them individually?

Primary text

If the two expiations are of the same type, the emancipation suffices for both, and each slave is deemed to fulfill one expiation. This is based on the established custom and legal convention that the freeing of a neck fulfills the expiation when mentioned generally. If the expiations are of different types, the ruling follows the previous dispute regarding the stipulation of specifying the cause.
