Replying to Switch tails, frontswap. Or is it?

I was walking and thinking about skiing, and I was thinking about a Switch tails, frontswap pretz 2. when you switch tails frontswap you go on opening the front foot so much that it's practically a switch tails 270 on.

My thought is how long do you have to ride the rail for it to be considered a frontswap rather then a 270. Its weird cause you could pretty much do that trick and have it being in this grey zone between 2 tricks. Should the trick get its own name? cause you are already front swapping, like its a surface 270. But when I do it I call it switch tails, frontswap.
