Default Back button focus

Finally , I was able to step into world of DSLR(D3300,18-55kit) and practicing now.
After going through many threads on focusing techniques, I have assigned AF-L key to Focus-On. Now the focusing is through this key and not half pressed shutter button. The method that I understood from the threads is 1) Press the back button to hear the focus beep and then 2) Press the shutter immediately. Is this correct?
Would like to know the advantages. I understand that if I shoot in burst mode, I can have the sharp frame when train enters focus point (Single point).
But how advantageous this method is, if I am using single frame at a time?
It may be possible that I use single frame at a time only for slow moving trains here. Please guide if I am correct. Thanks in advance.
