Same reason we make building with more than one entrance. Traffic.
Some types of ants only have enough traffic to need one (obvious) entrance/exit. (there’s usually a back door somewhere less obvious). Some types of ants have enough traffic that they need more than one entrance/exit. Could be due to the size of the ants, the size of their “cargo”, or just the number of them in the colony. Or any combination of the above.
