who knows about capping, page-14

From ANZ's announcement:

…The attached schedule identifies those listed companies in which the ANZ Group held shares comprising 5% or more of the total issued voting shares, and the ANZ's shareholding in those companies, in each case as at end of trading on 4 April 2008 and as a result of transactions entered into pursuant to the Opes Prime AMSLAs.

I concur with the view that perhaps ANZ has sold down below 5%.

It is therefore logical to assume that not all of the shares held by ANZ Nominees (identified by mydog in a recent post) relate to Opes Prime clients?

SO CAN ANYONE ANSWER THESE QUESTIONS?
How did the relationship between Opes Prime and ANZ Nominees actually work before this mess?
Is it the case that all shares acquired by Opes Prime were held by ANZ Nominees? OR
Did ANZ Nominees assume ownership of the shares after it appointed the receiver?
