It's basically the same technique- you need to create the shapes by manipulating the stroke in Illustrator. Once you get a few shapes down you can animate them and pre-render with alpha. You can then change the color, size and timing, comp several shapes on top of each other and create the animation that reveals the text.

In the absence of 3D Stroke – an excellent and indispensable product – you may be able achieve something similar with CC. Mr. Mercury.
Here's as sample. You can tweak the settings to suit your needs. The Base Comp is set to 60 fps for smoother motion then Time Remapped in the final. Copies of the Base are scaled, rotated and re-positioned to suit.
