**I'm not sure where people get the idea that you can't leave a baby to sleep alone in a room at all. The recommendation is that the baby sleep in the parents room, not that a someone has to be there anytime the baby is sleeping
You do have to be in same room for all sleeps even in daytime and evening.
"Place your baby to sleep in a separate cot or Moses basket in the same room as you for the first 6 months, even during the day."

I think what they are suggesting here is that you keep the baby where you are - ie, nap him in say, the living room in a basket if you are there.
However, this is basically shit advice and isn't backed up by any particular research. There's some reason to think it's better, overall, if baby can sleep at night in the same room as parents, though even that will not always work in every situation.
It's certainly possible to some extent to use a basket to keep the baby near you to nap in sometimes, and it can be an easy way to keep an eye on them, but it's not practical in many cases when you are moving around in the house much, in a bathroom, in a space where there is noice or other unsafe things for a baby.
This kind of awful advice is IMO one of the reasons we have so many mental health issues now with young mothers who are completely worn down because they can't even let their baby sleep in a safe place in the same house while they take care of their own needs, do housework, talk to friends, or all of the other normal things mothers need to do. It also drives anxiety and bad sleep patterns in babies as they tend to get noticed and often picked up even when they are having just a slightly disturbed sleep.
It's so culture specific too. Many countries with perfectly good infant health do not tell mothers anything like this, and the reason is it's not justified by the research. For that matter in some countries it's still quite common, and considered very healthy, for babies to sleep outside in a pram, even in winter.
