Sometimes an object is used only temporarily by a modules, while it's

In such cases, there are two reasons you might delete the object.  If
it uses a lot of memory you could free up the memory for other
objects.  Also you might want to clean up the module's namespace.

I del objects for these reasons sparingly, usually only when the
object uses a whole lot of memory, or the namespace is very messy.

However, I'm guessing that the person who wrote your code is just
overly paranoid.
