.Net StreamWriter.BaseStream, what does this definition mean? "Gets the underlying stream that interacts with the backup storage."

Question

Today I read on StreamWriterand came across this property BaseStream.

I searched for a definition and found this

"Gets the underlying stream that interacts with the backup storage."

from here MSDN - StreamWriter.BaseStream

I understand what BaseStream is for StreamReader, because this definition is very simple:

Returns the base stream.

But what does the definition of StreamWriter.BaseStream mean? Or more clearly, what does this part of the definition of “backup interfaces” mean? It sounds like gibberish.
