Not quite - mating types aren't sex (though the post confuses them). Their gametes are the same size (isogamy), so it's called mating types. Humans have gametes of different sizes, so we have sexes.
The opening line of that wikipedia article says they're "equivalent to sexes in multicellular lifeforms"
Right, "equivalent to" in the sense that legs are "equivalent to" fins in that they provide locomotion.
I mean, they are just for different environments. Fins aren't very useful for terrestrial animals, and legs aren't as useful for aquatic animals. Both provide similar functions suited to their environment, and are therefore roughly equivalent.
