When flying a twin on one engine there are basically 3 methods of preventing the yaw.
The 1st method uses aileron but no rudder and has no great merit.
The second method is to prevent yaw with rudder by centering the slip ball and rolling the wings level.
The third method is to apply 5 degrees of bank towards the live engine and use less rudder to fly straight.
Each method has its advantages and disadvantages. Clearly, if you have just taken off performance is your main concern so 5 degrees of bank towards the live engine will give you the most efficient configuration and best rate of climb. If you are instrument flying in the cruise, where performance is no longer a major issue, you may find it less disorientating to fly wings level with the ball centered and accept a little more drag and some sideslip.
The only difinitave publication issued by the CAA is CAP 528 Commercial Flight Instructors Manual. Part 3 Ex 23 includes teaching the use of 5 degrees of bank towards the live engine.
It is not uncommon for different techniques to be used in different countries. The whole purpopse of conducting asymmetric training is to present the student pilot with all of the problems and the solutions.
There are many different ways of doing things in aviation, they are not all correct neither are they all wrong. As a pilot you should know the relative merits of each and use your judgement to apply them in an appropriate manner.
