No it does not. If you look at the passages that the WTS uses to justify it's disfellowshiping, the situations where far different than what they interpret them to be.
Paul's only issue was safeguarding the church from those who were DELIBERATELY trying to sabatoge it. He was not saying that if someone committs a sin (even a serious sin) that he should be cut off from all family and friends. The ones that were to be avoided COMPLETELY were only the ones that tried to encourage others to follow their sinful course. 99.9% of those disfellowshiped today DO NOT fit in to that category.
We have plenty of examples in the Bible of people in various churches that had disagreements and differences in faith.
Also there is nowhere in the bible that says that one who has a different faith or no faith at all should be shunned. Paul and John both were interested only in protecting the church from corrupting influences. They were not speaking about punishing all those that had a disagreement in faith.
