"any advantage"
It depends what you mean by "advantage": when do you wish to use this command? What do you want it to do?
Many beginners write scripts that create lots of variables. Then the beginners want to get rid of their variables and so they write clear at the beginning of every script. The proper solution to this is not to use clear, but to write functions. It really is that simple! Advanced MATLAB users tend to write functions, not scripts.
Ditto for close and clc. These can also be avoided by reusing figures by keeping track of their handles, and not printing screeds of unreadable data to the command window.

The details given in the documentation are exhaustive.
In former Matlab versions clear all removed the breakpoints of the debugger. But fortunately this does not happen in R2015b anymore. Impeding the debugger is a bad idea.
After a clear all the functions are removed from the RAM and the reloading from disk wastes time.
