multiple layer styles

Question

So I was recently watching the videos from the developer conference. At one point one of the presenters jumped between layer styles. I'm not saying he changed the symbology, I mean it looked like the layer had 3 or 4 premade styles and he was switching between them. (not turning on/off duplicates of the layer)

how is this dark wizardry accomplished?

I rewatched that part a couple times to make sure my eyes weren't deceiving me, but I couldn't work out just HOW he was doing it.

Not really if the rest are turned off.  If the map json is larger (more layers and style config) I don't think it's going to load any faster, but I'd be pretty confident it's negligible in the scheme of things.

dang. not what I thought it was.

However it may still work. does having multiple versions of the same layer using different styles slow down the loading of the map?

Those are different layers but they are in a group layer with exclusive visibility. This will only allow one layer to be visible at a time inside the group layer.
