Another way of doing it uses three sticks and one person.

Put two sticks in the ground 20m apart so that they line up with targets 1 & 2. Move away from them and place the third stick in the ground so that all three line up. Remove the first and put it in the ground past the third one so that all three line up so that you are moving towards the target that is out of view. Keep doing this until the final target is in sight. If the sticks line up with it then there is an alignment.

Yes, that works too, though there is the possibility of a cummulative build up of error occuring if the method is repeated many times. That's why I chose methods that accomplish the alignment with only two sightings.
