Yes, the long crossover carries the hot coolant from the left head to
the junction piece where it joins the hot coolant from the right.

He said that long hose and the junction piece are already new VW parts.
Otherwise I would have recommended replacing them.
All 3 parts eventually fail, as would be expected.

I would change the oil cooler hoses as part of waterpump replacement,
something I consider a preventative maintenance.
