The code you quoted is just trivial example of "how to use
shared_from_this()", not "why to use it".
If you want to realise *why* such a feature can be useful, look, for
instance, at ASIO examples:
http://www.boost.org/doc/libs/1_37_0/doc/html/boost_asio/tutorial/tutdaytime3.html
Actually, there're lots of cases where you might want to make shared_ptr of
"this" inside a member function.
