From what I understand William Hill bought:
- Centrebet
- Sportsbet

but
-> paddypower owns betfair.
-> paddypower also owned sportsbet

Does that mean that:
William Hill, oversees everything since it also owns sportsbet.
Its unlikely paddypower would offer sportsbet to a competitor.
If they are not competitors then they are most likely part of the same company.

This means that if you place an arb between any of these for substantial money.
It may be flagged between this circle

The two companies are completely unlinked, It is two different sportsbet brands

That sounds like,

Toyota
and
Lexus

But then Toyota will definitely share parts of the business with Lexus
