I mean in a trace (from traceroute probing), 2 exchange points (in Mr
Woodcock's list) are next to each other.

.... ip of AS1, ip of EP1, ip of EP2, ip of AS2, ....

I thought they are connected to each other directly (probably the
connecion is not as simple as the p2p link between 2 routers).

Sorry, I did confuse peering with transit. But I thought those private peering
points are somewhat similiar too the IXs, ISPs exchange traffic there and they
may also provide transit to the customers there.

Is this case very common?
