How can a buffer size be a sliding window?

Is it dynamic? If you find out it is, you're more than welcome to present
those results to us!
And the answer to most "whys" is of course that someone has to figure out if
that is the case, and then write a decent implementation that acts

I would expect that to be good questions to someone with a fine insight on the
inner workings of the TCP/IP stack you use. I would also assume that it will
vary between implementations.
