Looks like my intuition is indeed be wrong! https://github.com/scala/scala/blob/master/src/reflect/scala/reflect/internal/util/Position.scala#L41

So, this is a no problem, hence [this](https://github.com/dotta/scala/commit/24927c880ef672254bfdefda1ee4c09adc03b71c) implementation is correct. So, unless someone disagree, I'll squash the commits and add the additional information in the commit message. \cc @dragos
