If this is true, it seems to me that forming a mob is only a good idea for low hit dice monsters. I don't have DMG II though, nor do I have my books with me. But it would be interesting to see an analysis for mobs of humans, mobs of lizard folk, mobs of medusae, etc., to see how beneficial forming a mob actually is for a monster at different HD.
As presented, Mobs don't form voluntarily. The creatures don't gather until any specific number is reached then "flame on" to mob status. The examples are a Riot (mob of humans) and Stampede (mob of Light Horses).
A mob is a cluster of emotionally charged creatures acting on emotion and not reason. In fact, they are unable to make any attacks that would require the individual members to take an action (no spells, spell-like abilities, breath weapons, etc. can be used). Continuous effects, like gaze attacks, function normally.
