'The asset' in my statement obviously refers to shares in Uber. Those aren't 'in public markets'.
Moreover, even if I were talking about assets in general, including those traded in public markets, my statement is still true. If company A buys shares in company B, and company B's share price subsequently goes down in value, then company A may mark down their own holding (i.e. reduce the value they report in their accounts) to reflect that new reality. But that reality (the lower public market value) preceded the mark down. So the mark down cannot be the cause of the reduction in value.
In simpler terms, 'marking down' is an accounting activity, or one of financial reporting. It's writing down what is. It's creating the reality. That's why it's called 'bean counting'. The beans exist before they are counted.
