I now see your mistake. Sadly he looked much better in the last two years of his life when he was basically disabled.
The picture you see here was definitley nin vuv, I was there myself. If you need proof that it was then, you will be aware that only in the last 2 years did they bring the Rebbe out into the Beis Hamedrash, in that special section that could be closed off. Otherwise he would have been sitting at the head of a tish. He was only brought out for about 10 minutes.
Before he fell down and got a blood clot in the brain, or wjatever exactly happened, he had parkinsons as well as some other trhings, and he couldn't walk withoput help, and shook very badly, and his head was on the side. The operation to fix this was considered too dangerous, but when they had to operate anyway to fix the intercranial bleeding, they fixed some of his other problems too,which is why he looked much better.
