Horizontal transfer seems to be the best explanation.
As far as I can work out from Atkinson's expansion clip, Balto-Slavic and Indo-Iranian are almost at opposite extremes of the IE range, rather than neighbours. This looks like a mistake. Perhaps they can rescue it by making movement across the steppes easier.
