The manual notes some of your concerns - especially the lack of a need to do a 'seeding' and (since 5.2.1) the presence of a new algorithm that generates a unique sequence regardless if the 'seed' is repeated. Furthermore, since there is no need to do a seed, I would guess that each call to the function mt_rand utilizes a new 'seed' internally, which the developer need not worry about.
