Why an old one when a new beveled bushing came with the pipe?

The package came with the following:
- One elbow pipe with only one threaded end
- Two plastic nuts
- One beveled washer
- One squared washer

I used the beveled washer for the non-threaded end of the pipe.
So that left me with only the squared washer.

Looking at the instructions, I'm supposed to use the squared washer.
But, nothing I did made any sense.

So, in exasperation (with my sister asking what was taking so long
to follow the simple instructions), I just re-used the old beveled
washer.

But, I really wish I understood how that squared washer was supposed
to work - because I couldn't figure it out!

Googling, I see almost everyone uses TWO beveled washers (one on
each end), so, it's confusing to me why the squared washer even
exists.
