question on constraint 47 (3) - wasAssociatedWith-ordering

Hi All,

Can someone clarify the following in the spec (Constraint 47 - 3)

IF wasAssociatedWith(_assoc; a,ag,_pl,_attrs) and wasStartedBy(start1;
a,_e1,_a1,_t1,_attrs1) and wasEndedBy(end2; ag,_e2,_a2,_t2,_attrs2) THEN
start1 precedes <http://www.w3.org/TR/prov-constraints/#dfn-precedes> end2.


>From my reading, this is saying that the start of activity a, must happen
after the end of activity, a2 if the the agent, ag, ended activity a2.

This doesn't make sense to me. An agent can  potentially end one activity
and start another...

Can someone clarify this for me?

Thanks
Paul
