But could they be portions of the unspecified interval?

How come? It's true that "I travelled on Monday and I travelled on
Tuesday and I travelled on Wednesday". But that's not entailed by
"travelled on Mon joi tues joi Weds".

That means (on your story) "travel twice, there being exactly 
one travelling per three-day period".

Probably the best way to get the meaning I gave is 
{re roi ca ci djedi}.

   {re da poi ke'a djedi se ka mi zvati la paris ca ce'u} 

is true. But 

   {re da nu mi zvati la paris ca da poi ke'a djedi} 

is not necessarily true. Criteria for delimiting events are rather
vague & (IMO) flexible.
