I guess the "Blockchain" part.

Blockchain is a decentralised way to create trusted record without a trusted counterparty, i.e. centralised.

In this case, there is nothing decentralised, you need to go through IBM as with a regular system. Blockchain is only mentioned as marketing to convince you they are reliable. A bit how some hosting service tell you their are using S3 to convince you they are not going to lose your data.

edit: The problem is the title of the article that let you imagine there is some interesting blockchain tech being developed. Instead that's about as interesting as "Walmart uses SAP"
