If you are doing this in a ForEach type of loop, then you should accumulate the results in a group or list. Then, do the Export outside the loop (i.e., when it's done). The file will then have all of the accumulated points. If you are doing it in a Sequencer-based loop, then yes you would be overwriting. In that case, pass the output of Sequencer to Format to create a unique file name for each iteration and pass the filename to Export.

I have been trying to work with DX loops the last few days for a different purpose and now believe I understand the difficulties better. What may be happening with you is that a new file is being written for every point, overwriting the previous one, so that what you end up with is - of course - a file containing only the last point. It's all there in the User Guide (section on iteration), but it takes some working out. I can give you further pointers if you need them.
