When doing a 'create sequence diagram for selected element' on an operation in class - the diagram has it's lifetime in pieces. Because it's one, synchronous operation - this should be one. Or at least there should be a way of merging two neighbour calls.
in my opinion it's more like presentation options instead of defect, each synch call inside an operation may be considered as call itself or as part of one execution specification. it may be good to allow merging, but it also require good handling for splitting. in 6.1 there was number of isses with split after occasional merge.
