Not quite. It is not impossible that they are the same, there's just no
guarantee that they would have a relationship.

a) people never bothering to enter their data
b) third parties entering data for other people (in databases that don't
   prevent this)
c) noone bothering with clean-up (especially in case b)
d) decreasing availability of necessary knowledge as struggling providers
   exchange their skilled employees for cheaper ones. I.e. not only
   clueless end users (that's normal), but also clueless transit providers

The closer you are to an ISP or ISPs that filter their customer prefixes
and aspaths on IRR data, the better the data is likely to be.
