Velocity is a vector quantity.
So,if two velocities happen to be parallel to each other(same or opposite direction ),they are added algebraically.i.e.mere sum or difference as the direction would be same as the two given vectors.

What made u think that resultant can be in diff. direction
Even try using the triangle law .It gives the same result.

Velocity in the same direction, say x-axis, will have only one component each. So they shall add as two vectors - so u have to be careful of the displacement coordinates, to get the resultant.
---> addition process.

Coherance.
Example: Light travels at 186K Miles per second. So we have our velocity.
Light that is made coherant, which is very close together and going in the same direction - becomes a laser.

if the direction is the same then ,..the velocities will add up.
if it is vertically opposite,..then they'll dorectly subtract.
but if its anyother direction than a 180 degree staight line difference,...then u will have to apply vectors

velocities are vectors and therefore it has to be added vectorially.
