In UML/SysMLv1.x Lifelines do not have specific information about the times or time ordering of events (such as Message arrival/sending) of other Lifelines

The “hybridSUV” lifeline represents another interaction which further elaborates what happens inside the “hybridSUV” when the vehicle is started. Source OMG Systems Modeling Language (SysML) 1.6
The lifelines on Figure D.10 (“whitebox” sequence diagram) need to come from the Power System decomposition. This now begins to consider parts contained in the HybridSUV block. Source OMG Systems Modeling Language (SysML) 1.6

On Communication Diagrams, the Messages are decorated by a small arrow in the direction of the Message close to the Message name and sequence number along the line between the lifelines ... Source OMG Systems Modeling Language (SysML) 1.6
Figure D.9 shows a “black box” interaction, but references “StartVehicleWhiteBox” (Figure D.10), which will decompose the lifelines within the context of the HybridSUV block. Source OMG Systems Modeling Language (SysML) 1.6
