Let's assume that it's true. If it is true, then it is likely instinctive. If it is instinctive, then it is beneficial from an evolutionary point of view - it promotes the survival of the man or woman. So, we can look at our ancestral tribal environment to come up with a reason. The survival of males, as hunters and gatherers, would depend on knowing where fish, animals, and other food can be most easily caught. This would best be kept secret, or the areas would be exhausted by others. One of the critical roles of females in the ancient environment involved family and social linkages - knowing who was trustworthy, and who was or wasn't useful in establishing the success of the tribe. This knowledge was vital in ensuring good behavior within the tribe. Being well-connected, i.e., having this knowledge, was a sign of a successful and valuable woman. It was therefore evolutionarily effective to provide this information when needed. So we can come up with a plausible reason why the statement is true. I'll bet I could come up with just as good a reason that men can't keep secrets, but it's lunchtime.
