I haven't really been following the sidechain developements, but my
understanding was that redemption from a side chain would be two phase.
The person unpegging the funds provides a proof that they have locked the
funds on the side chain and are eligible to withdraw the funds, plus they
put up a bounty. Then there is a time-locked period where others can
collect the bounty by providing a fraud proof, that the locked funds given
in the proof have actually been double spent. This two phase system
doesn't violate this rule.
