So the gemara was sharing a interesting piece of information that is of no practical use?
Even if it would only apply to the most selfless person ever, who truly davened for her friend to get married not thinking about herself. So when the davener gets engaged first is she disappointed since she really wanted and davened that her friend should get engaged?
Of course this is possible, but I assumed it is meant as others describe it if you want to be answered in something daven for someone else
