This doesn't make sense to me. Wouldn't current stop flowing once they
had both reached the same terminal voltage?
When you start drawing current, the one with the lower internal resistance
will tend to supply more than its share, but since internal resistance
goes up as the battery discharges it should even out somewhat.
