Topic: Pouring off liquid ‎ from a mixture

Very quickly review the second case of the משנה דף קלט: “נותנין starting with – ומסננין את היין בסודרין ובכפיפה מצרית

And the גמרא דף קלט: “ובכפיפה מצרית (two dots in middle of the wide lines) until the bottom of the Amud

Why is it permitted to pour off בנחת?

What is the Gemara answer as to why it is permitted even filtering out the droplets?
