2a and Poi Dancing

So I have this friend that’s been learning Poi for a good few years now, and the other day she was showing me a few of the basic moves. What struck me though was the similarity between some of the moves and a few 2a tricks.

So I guess what I’m asking is, has 2a been influenced by Poi or is this just a case of two very different things that simply appear similar due to my lack of knowledge about either subject?
