No, this isn't stretching. It's an attempt to equalize string tensions in
segments on either side of a high friction point by forcing string past the
friction point in, hopefully, the right direction and, hopefully, by the
proper amount. If all the string segment tensions in any given string are
equal when you're done with the tuning, the short term stability of the
tuning will be better. Little effect will be had on the long term
stability, which is essentially climate related.
