It does. When I tune (warning - I am novice) I tune middle octaves, then go up and down the scale with octave intervals. And then check the whole instruments tuning notes that sound off. String itself stretches and loses the pitch a little sometimes, especially if it was out of tune by quarter tone. But more importantly string peg that holds the string is just screwed into the hardwood board. So when you tune it, you still have some room for it to settle. Even slight press with tuning hammer on the peg can result in big difference in tune. Especially on high notes.
