My understanding is that the pledged delegates, awarded during the primaries, are not supposed to switch until after the first ballot.
I think superdelegates can do absolutely anything they want (although they have to worry about their repuation if they break a promise to a powerful politician).
In any case, do we think that a superdelegate will be arrested and face jailtime for "voting wrong" on the first ballot?? The outcome will not be known until August, no matter what the media tells us.

I think that's what bio is saying. The "pledged" delegates - awarded based on the primary vote - are required to vote as pledged on the first ballot, but after that they can switch.
