One of the great things about I2C is that multiple devices can be hooked up to the same I2C bus if their addresses are unique. In some cases, a part may have a fixed address and therefore it is impossible to use more than one of the devices on the same bus or in another case, two different devices may happen to have the same fixed I2C address which also creates a bus conflict.

You may also want to separate a large number of devices on a single I2C bus into several smaller buses due to loading concerns or for bus isolation.
