Many of the cheap lamps have neither a 4 way block so the fitter has to find an extra chock block or any junction box area which has resulted and many junction block being just shoved into ceiling space. Not really correct method and they really should have a junction box fitted but in many cases just not possible. The loop wires cause many problems with DIY'er as they do not connect to lamp and in many cases the lamp has two wires of the same colour going to both Line and Neutral the Line often has some tape on it to show it is the switch.
So in most cases you will need to change the three way connector for a four way connector the fourth connection called loop does not connect to local lamp.
