Given that Neo and Morpheus added their total momentum together.
Let's answer the given question given that momentum is conserved.
Here, we are to apply the Law of Conservation of Momentum.
The Law of Conservation of Momentum states that the total momentum before collision is equal to the total momentum after collision.
Where momentum is conserved in the absence of external forces.
It can be expressed as:

Therefore, their total momentum before the collision is the same as their total momentum after collision, so momentum is conserved.
ANSWER:
The same as
