I would classify it as two. You had dealt with the first encounter and now a second was starting.
If the situation had been one in which the second group were specifically designed as reinforcements for the first -- such as X rounds after the first group enters combat reinforcements arrive -- then I could see it as one encounter. But as you describe it I see it as two.
In our case, we saw the new enemies right as the last guy fell. These weren't reinforcements to the first, they were another faction. Literally, we started our next turn with, you see Lord Whathisname and his trops at the outskirts of the village. His men will be at your current position in 4 rounds. what do you do?
In our case, we opted to have half the party hold position, the other half run around and try to circle in from behind. The barbarian was part of the group that was running.
Note I said run. Narratively speaking, the barbarian just raged, and should be exhausted for a while. By saying it's 2 encounters, per the rules, the barbarian is getting an instant recovery, which makes no sense.
My DM has a tendency to run adventures like the 2nd Pirates of the Carribean (a common comment by us all was our DM must have directed it). He packs on encounters with little breathing room.
From my perspective, I have a problem with using an Encounter as a unit of measurement for duration. Because when they're stacked, the line blurs.
From a DM planning standpoint, they're pretty obvious, kill group A, then bring in Group B. Calculate XP for Group A, then group B.
From an ability duration/limit perspective, they make little sense.
