OH, will that is the answer then.
2 masks can not be linked while making the path.
Thanks, Sorry for the wasted time.

It turns out there is a SIMPLE way to have BOTH masks follow the same path, on a single layer.
1) Create your first mask.
2) Create your second mask (either inside the mask or anywhere else, doesn't matter)
Then, to animate both masks to follow the same path simply:
Highlight all the points (vertices) for BOTH masks and adjust/move the points to any direcdtion you want.
By highlighting all the points it connects the 2 masks and treats them as one.
It's the same thing as animating a regular mask, but just highlighting both will control both.
Easy Breezy.

P.S. control + A might not highlight all the points on both. I use the regular pointer, click hold and drag to highlighted all points manually.
