Commentaire sur La Genèse 50:1

וישק לו, he kissed him. The emphasis in this verse is on the word לו. Joseph kissed "him;" had Jacob been dead it would have been forbidden to kiss him seeing that the corpse exudes ritual impurity, and that impurity rises up to heaven and would harm the person who does the kissing. Inasmuch as Jacob had not died, however, Joseph was able to kiss him; Jacob simply appeared to be in a coma.

ויפול יוסף, not only he but also his brothers, of course. Seeing that he was the most highly placed of the brothers the Torah mentions him. If he allowed himself this display of emotion, his brothers surely did no less.
