Huh?

I just saw this story from ABC last Friday, about Lachlan Murdoch's resignation from News Corp. One bit near the beginning caught my eye:

The sudden departure put the spotlight back on the issue of who would eventually succeed Murdoch, who is 74 years old. The next most likely candidate in the Murdoch family is Lachlan's 32-year-old brother James, but given his youth he would not likely be a candidate for many years.

Excuse me? Lachlan, as the article says later on, is 33. The last time I checked, 33 - 32 = 1; James is one year younger than Lachlan. So how, exactly, is the passing of the torch from Lachlan to James complicated by the latter's relative youth? Explain this, please.
