From the said article:
"The new marriage constitutes a legally binding relationship. As stated in the November 15, 1979, issue of The Watchtower, page 32, “now he has entered a new marriage and so cannot simply end it and return to the way things were before; the former marriage ended with the divorce, adultery and remarriage.”
and
"Although the new marriage would not be viewed as adulterous, the man would not qualify for special privileges of service in the congregation for many years and not before living down any notoriety or reproach associated with his wrongdoing."
and
"This adjusts our previous understanding that such a marriage would be viewed as adulterous until the innocent mate died, remarried, or was guilty of sexual immorality."
So, it doesn't change the fact that entering into a new marriage while not being "free to remarry" constitutes adultery, it only changes that the new marriage is considered legally binding and sacred, regardless of the status of the "innocent" mate.
