There is at least this from Zuckerberg's announcement : "Calibra will be regulated like other payment service providers. Any information you share with Calibra will be kept separate from information you share on Facebook."
I don't mean that as pure snark; I'm dead serious. The legal definition of all those things, the definitions they can get away with using, and the definitions that a normal person would expect from reading that sentence are probably three very different things.
Plus, along with general lack of confidence in Facebook keeping its mitts off of juicy data given their checkered history, I have even less confidence that the promised wall will be there going forward, and that there won't be an excited, breathless announcement in a year or two about how ecstatic they are to bring you awesome new services powered by the data they're going to get from tearing down that wall and isn't it all just so wonderful.
This is a PR statement. Facebook and Zuckerberg have straight up lied about this sort of thing before [1].
No need for complexity (they’re weaselling their words) when telling it simply (they’re lying again) will do.

Personal information only, such as your full name.
Does not include an ID that facebook is able to link. Does not include your transactional "records", which are not information.
> kept separate:
Means it is stored a separate database, however it can be connected together.
> Facebook:
Refers to "Facebook Inc", but not "Instagram LLC". Instagram is authorized to share information with Facebook.
This has applied to a bunch of things for years now. Have you flown on an airline? You might well have flown on an airplane operated by a different company, with that airline's branding. Who makes your car and your electronics? The details of all that have been a complex maze since the 1980's. Who makes your toothpaste, and where are all the ingredients really from?

I'd be shocked if Facebook weren't planning the same thing.
They promised not linking accounts between WhatsApp and Facebook, inevitably broke it, and faced triple-digit millions in fines, without a sweat: https://www.theverge.com/2017/5/18/15657158/facebook-whatsap...
Keeping data separate is not interesting wording by itself, imo.
In separate sql-like tables with a key to join on.
He lied. Again and again and again.
