My position was eliminated in July 2009 - but has now been rehired

In July 2009 my position was eliminated. I was a Food and Beverage Director. My position was recently "reinstated" and filled by one of my past associates. There seems to be no change in the duties that I was responsible for and the duties of the current associate. This was not an increase in tasks, as the assoicate that secured my positon was also replaced.
I had a very successful career with positive reviews and no discipline for over 10 years. The hotel did have a new General Manager that did make comments about my commitment and dedication to my position - and also was heard saying that I was not productive enough and was not sure "what my positon entailed since she had never worked with the postion prior"
I now am under the impression that the elimination may have been personal.
Please advise
