Clarify that a pool represents a single BPMN process, not a "participant" meaning role or business entity. At least do this for a white box pool (aka private process); a black box pool (abstract process) is empty of activities, so its process is unknown and often labeled as role or business entity. Also remove the language that multiple pools in a BPD are about B2B. This is rarely the case. Multiple white box pools in a BPD are used when the processes involved have independent lifetimes and cardinality, and almost always when both pools represent the same business entity not B2B.
