MBS's Originated by WMB were then "sold" to it's subs such as WMMSC, WMAAC, Long Beach etc and then sold into Trusts they created, portions of these assets were usually retained by the sub/company as investments.

For your premise to be true, there needs to be direct or possibly indirect title to those assets or their cash proceeds that were pledged to WMI/WMIIC and also that those sub assets were NOT sold to JPM along with WMB.

It is most likely the case that those "retained assets" were shielded from WMB, as the Originator of the loans that were packaged into MBS's since that was a requirement for such assets to qualify as a "True Sale".

To this day while there is some circumstantial evidence that may suggest that this could have occurred there still lacks any real evidence or factual proof that such assets or cash proceeds are forthcoming.
