They are generally in unison. The top Eupho part is for people who read treble clef baritone/euphonium, which is a (Bb) transposing instrument (like trumpets). That's why it reads a note higher than it sounds. A better way of saying that is that it sounds a ninth lower than written :) Hope that helps.
