I’m pretty sure the risk is lower, but you probably still shouldn’t. I think the problem is that anything fatty/oily can emulsify with other things that get poured down the drain and potentially thicken into a blockage even if they weren’t in that state when you poured them down
I’m with you, it’s confusing. But I think what it means is this:
The study ran for 90 days. Non-sterol bees had stopped doing bee sex by then. Sterol bees were doin it all the way up to the end of the 90 days - and then the study ended. We can therefore assume they wanted to continue having freaky beedsm sex for even longer.
