It's so the male duck can scrape the semen of any previous partners out of the female duck's vagina. This was a random mutation that somehow became dominant because it perpetuated the species. Unlike leaving all that semen in there, which ... wouldn't ... have?

Remember, sexual selection favors traits that benefit the carrier, being able to have a mate exclusively bear their offspring and excluding competitors would favor their genes, unlike the mate potentially bearing offspring from multiple contributors (even within a single clutch, but I’m not sure about that part, not a biologist)
