I'm a little confused about independent sleep increasing SIDS. As far as I know, room sharing does decrease SIDS, but bed sharing dramatically increases it
Yes, you're right, bedsharing does increase the risk if the mother has smoked, drunk alcohol, or taken drugs, or the baby is formula fed, sick, or swaddled, or they are sleeping on a very soft bed with lots of bedding.
But for mothers and babies without these risks, cosleeping increases breastfeeding success (often termed as breastsleeping) and reduces risks of SIDS by changing how the baby sleeps. That's why health authorities in the UK, Spain, and Norway no longer recommend against cosleeping. And telling mothers without risk factors not to cosleep increases the risk that they fall asleep on sofas or in chairs, which then itself increases their risk of SIDS.

And this paper gives an anthropological perspective on the changing scientific views on bedsharing/breastfeeding over the last few decades: https://www.researchgate.net/profile/Cecilia-Tomori/publication/334322280_Toward_an_Integrated_Anthropology_of_Infant_Sleep/links/5ef4e6b6299bf18816e7f7d4/Toward-an-Integrated-Anthropology-of-Infant-Sleep.pdf
But many of the guidelines haven't yet caught up with the science.
