No, they are same, silly! Join the round-block up into a circle. There 
are 8 changes of method, the same as in the snap-finish. They would have 
been different if the the last method was Belfast, of course, because 
then the round-block has an extra change.

Note that, treated as a two-part, the second composition also has four 
com per part. This property holds for all strict multi-part round-blocks 
in the "proper" way of counting com.
