Side Trips on a Oneworld Explorer Pass
 

I am wondering if this pass allows side trips such as
CDG-MAD-CDG and CDG-MUC-CDG as part of an BNE-SIN-CDG-DUB-SAO itinerary ?
The OW website talks about "Your route from one continent to another must move forward in a continuous westward or eastward direction. However, there are no backtracking restrictions so you are free to roam locally at will within a continent as long as you don’t go back to your point of origin."
Is their "point of origin" BNE or CDG?
Thanks,

BNE is your point of orgin.

If you are going to do a one world explorer (continent based) you get 4 flights but 2 stopovers in Aust. These can be first or last. If last BNE or any other city must be the last flight. When you get back to BNE the ticket is completed

Except for the continent of origin, there are almost no restrictions on how you route yourself within a continent. You can use a city as a hub, if you want to, and pass through as many times as your segment total for that continent allows allows. (4 or 6 free, two more for a price, 20 total for the entire trip.) There are some nits about only one cross-country in US and OZ, and only one "long" trip LHR-far away-LHR.

As noted above, if you start at BNE, once you return to BNE you'll not be allowed to fly any further segments. Also, in continent of origin they limit stopovers to two - other places there's no limit, just the segment count. Stopovers are 24 hrs or more, so you can do some quick stops if it pleases you.
