BPMN11 — Clarify whether pools require their activites to be centrally coordinated

Clarify whether pools require their activites to be centrally coordinated. In particular, above Table 85, the specification says: "Note that Message Flow cannot connect to objects that are within the same Participant Lane boundary." (I think this should say "pool", rather than "lane".) Does this mean the entities represented by lanes must not coordinate their activities directly through messages to each other (ie, the coordination must be centralized)?
