While we've had Polio vaccines and Malaria pills for years in much of the western world, much of the poorer parts of the world aren't so lucky. So instead of duplicating something that already exists and works well, partner with them and get it done faster together.

What is the point that I'm missing? They don't really want to cure all diseases?
“Thank you mark, it’s an honour to join you all after this incredible milestone. The Chan Zuckerberg initiative is already doing some very promising work in terms of improving education for all students (and so) that is a really thrilling thing.
And it is amazing that today they are taking on another bold challenge, this idea of curing and preventing all diseases by the end of the century. That’s very bold very ambitious, and I can’t think of a better partnership to take it on,” Bill Gates said.
But it's not clear there's any reason or benefit for them to be under the same central organization.
Plus they will be greatly incentived when working under their own label 'Chan Zuckerberg Institute' to make their own lasting impact on the world. Just pumping more cash into Bill Gates existing project isn't a very exciting driver. And motivation/morale is important with any big project.
Curing "all" disease is a bit more ambitious.
Not to say that in the end, Gates isn't helping more people today.

Which I don't mean as a criticism, it's just that they aren't really driving the effort, they are participating by providing a lot of resources.
I'd consider the entity with the most money in the game as the driver of really anything.
Both groups are needed, of course. But you giving the example of "curing" polio as an example of what the Chan Zuckerberg foundation is trying to accomplish is inaccurate.
I just think other than the prestige argument (which is likely what this is) they could actually do more work working with someone who literally spends more on this than the entire USG.
