This would be tough to do in After Effects. Expressions don’t have access to mask info.

Can’t do it with native After Effects. Check out Color Sampler in Digital Anarchy’s Anarchy Toolbox.

Try this:

v1 = 25;
v2 = 2500;
t1 = 0; //start time
t2 = 5; //end time

if (time <= t1){
  s = v1;
}else if (time > t1 && time < t2){
  t = time - t1;
  T = t2 - t1;
  k = Math.log(v2/v1)/T;
  s = v1*Math.exp(k*t)
}else{
  s = v2;
}
[s,s]

This might give you some ideas. Select your mask shape, copy it, and paste it into the “Flare Center” attribute of a Lens Flare applied to another layer. That will give you a 2-second animation of the flare moving around the mask. Set that layer’s blending mode to “Screen” so you can see the layer with the mask. Apply Stroke to the layer with the mask and keyframe the “End” parameter going from 0 to 100%, with it reaching 100% at the last keyframe of the Lens Flare.

I think you could do this with an expression selector applied to a text layer, but you’d probably have to use a mono-spaced font. The expression would have to know the final destination of each character (i.e. in your Rich Cliffard/Cliff Richard example, which “i” ends up where?) and the move order (unless everything is moving at once) and whether the characters are moving at a constant speed (pixels per second) or a fixed time. Stuff like that. It’s not trivial, but it’s doable.
