Difference in scope of argument and return value [closed]

The example below is a no frills version of something I saw out in the wild.

class Client(object):

    def __init__(self, session):
        self.session = session

    def _get(self, path, **kwargs):
         self.session.get("etc")

def ScopedObject(cls):
    return cls

ScopedClient = ScopedObject(Client) # Why??

What is the use of the last line?

Here is an example I tried out to make sense of what happening. (Code above is simply for context).

>>> class A:
...     def __init__(self, v):
...             self.x = v
...
>>> def scope(cls): return cls
...
>>> a = A
>>> b = scope(a)
>>> a
<class __main__.A at 0x10989c2f0>
>>> b
<class __main__.A at 0x10989c2f0>
>>> a(1)
<__main__.A instance at 0x1098df910>
>>> b(1)
<__main__.A instance at 0x1098df870>
>>> a(1)
<__main__.A instance at 0x1098df910>

So, okay it causes their instances to be different. But I could have accomplished the same thing by doing:

>>> c = a
>>> c(1)
<__main__.A instance at 0x1098df870>

Which returns the exact same instance as b.

What am I missing?
