Well it represents the underlying structure of the data. What is basically happening here is that when a particle is emitted, it uses the position of that particle to find the closest position on the surface it was emitted from and saves that position on the surface and all the information it holds as "EmitLocation". You could do the same by using get closest location on geometry with the surface you emitted from.
That location - be it from EmitLocation or generated by you - the holds all the information of that surface for that specific point on it. It holds Position, Normal, weights, vertexcolors and whatever might be on there. What you do now when plugging that location into the source of a get data node, is telling that get data node to try to retrieve its information from that location, which gives you access to for example the value of the weightmap at the surfacepoint closest to the particle.
