The observable universe isn’t the same as the local universe. The observable universe encompasses a region of approximately 13.7B light years from our point of observation which is earth, the local or near by universe is limited to about 1b light years. Both have their usefulness when conducting observations as we need to take certain assumptions based on what we know. The former is anything that is currently within our cosmological horizon the latter is anything we can observe that is in the same relative slice of time or cosmological development stage as us.
