It's because in the first sequence, each entry differs in only one bit whereas in the second sequence the transition from 01 to 10 changes two bits which produces a race condition. In asynchronous logic, nothing ever happens at the same time, so 01 to 10 is either 01 00 10 or 01 11 10 and that causes problems.
