If the IO found grounds that you broke your residency in those 2 months then yes they can re-set your clock. If you were say renting a place and working in the other country for 2 months, that then can show the IO you are not maintaning US residency (even with owning or paying bills back here).
It is all about what you are doing over in the foreign country that makes the decision, and not the time spent over there (unless after the 6 months, then it becomes a lot more in the favor of the IO to re-set the clock).
If he found resaonable evidence you werer not just mearly visiting on vacation or visiting relatives etc, but engaged in employment etc, then that would be all they need to prove you did in fact break the residency cycle.
I don't know about your details on your 2 months away from the US to make any assumptions. I'm just saying this is one way that an IO can re-set the clock after only a couple of months.
There have been several cases like this, so it's not all that uncommon. Under 6 months the IO has to prove you broke residency, after 6 months away its you that has to prove it. If he has the proof, then he can do that...
