Using the version extension and a symbolic link isn't necessary, but it is 
helpful. What it helps with is making it clear exactly which version of screen 
you're running. You invoke the command without the version extension, and that 
finds the symlink. It then points to an executable that's named after the 
version. That way, purely for administrative purposes, you know what you're 
running. It also allows you to install different (in this case) screen versions 
and easily switch between them. So it isn't magic - it's just good system 
administration.

Not if what you already have works.
