Additional purchses of the feat give you an additional supernatural ability of the form, not an additional use, otherwise the word "use" would probably appear in the special claus at some point.
While the feat would be more balanced if it were only 3 / day, that is not how it reads. The languages parses out very specifically. Whether it was intended to allow any number of (Su) abilities per day, but only 3 uses of each specific ability is unknown, but a it is written it works like this:
You metamorphosis into a creature, we'll say a beholder. You use his antmagic cone for three rounds, and then metamorphosis into another creature, perhaps a choker. You use his quickness for three rounds, and then turn into a beholder again. As you have already used the (Su) ability of anti-magic cone, you cannot us it again that day, but you can take the (Su) ability of eye rays and use them 3 times.
If you take the feat twice, then every creature you transform into grants you two (Su) abilities, each of which is usable 3 times per day.
