The gemara on the bottom of amud alef says that 1 reason can not be learnt from 2 pesukim. It then asks 'what is an example of this?' and continues to search for an example until they reach a conclusion in the middle of amud bet. What is the point of this? If there is no such thing as this, why does the gemara attempt to find a case and the case that they arrive at is anyway not dinei nefashot?

The Gemara is merely bringing an example to illustrate Ta'am Echad mi'Shnei Mikra'os. The Gemara seems to say that if the Derashos are not exact -- but there is a Nafka Minah between them -- it is not considered Ta'am Echad. However, the Aruch la'Ner writes that even in such a case the Halachah will be that they are counted as one, for the Derashos are mutually exclusive in any event. The Gemara was simply looking for a case which fits the phrase "Ta'am Echad mi'Shnei Mikra'os."
