All three links split the available rank but only one is credited to the receiving page
Are you sure this is the case when all three links are identical and point to the same page?
Whilst MC did say that only one will pass anchor and PR, it did not say that having a duplicate links pointing to the same page is PR drain.
Not that I know any better as what he said can be taken one way or the other.
