I see part of it, but shouldn't the current in I3 flow the other direction?
Whether the actual current flows in the other direction or not does not matter; it simply means that when the equations are solved and calculations are completed with the assumed direction, it will yield a negative value for that current.

Take the assumed directions as given and write the equation from them.
