Can inherited arity be overcome?

Question

I have this class / object diagram:

I do not understand why this object diagram is not valid according to this class diagram.

In an object’s diagram, one C object has two links with two T objects, an alpha link to the T object and a beta dependency to the other T. Therefore, I don’t think this violates the multiplicity restrictions.

Could you explain to me why the object diagram is invalid?
