What you linked to has nothing to do with SR or even congressional testimony. It's filling out the rest of their money-transmitter issues. First, they seized funds from Dowalla, and then from Wells Fargo. This was the WF seizure.
Seizing MtGox's USD funds may have had an effect on SR, but that wasn't the reason why they were seized. It was a money laundering issue, plain and simple. Remember, the funds were seized by DHS and the FBI was in charge of the SR case (which wasn't even against SR as an entity, but the owner/operator as a private citizen). I'm sure the FBI and DHS probably share data, but that would have required a lot of interagency cooperation for what is a pretty small matter. DHS was more concerned with blocking the money laundering possibilities than they were with blocking SR. Granted, DHS may have learned about MtGox from the DEA/FBI while they were investigating SR.
I wouldn't assume the gov't really cares that much about Bitcoin. They just want the players in Bitcoin to play by the existing rules.
