I think that the reason they put it upstream of the turbo is that the pressure in the turbo inlet duct will always be slightly negative so it'll scavenge crankcase vapors.
You're spot on about the reasoning for having the coolant pipe in the PCV tube. If drops of condensation make it out of the PCV hose and land on the turbo impeller, it will experience spot cooling, which will weaken it and lead to eventual failure. I don't think that the ambient temperature needs to be all that low for the temp inside an unheated PCV hose to be below the dew point for crankcase gasses.
