My understanding is that point-biserial correlations are measured between a binary (bernouli) variable and a continuous (interval or ratio scaled) variable. Therefore by definition you cannot have a point-biserial correlation between 2 bernoulli sequences.
If you clarify what you want (maybe give an example or partial example) we can give better help. -- Gregory (Greg) L.
