every_operation_can_be_activated_together counted one block per operation in the chain, which was true only while every operation was a point function. A neighbourhood operation is a dispatch of its own and emits no fused block, so the count now excludes the operations the detail chain names, and each of them is separately asserted absent rather than the comparison being loosened.
