buffer-undo-list actually supports storing point positions.
So, if one wants to implement what you want, it is certainly possible by
doing something like

(let ((buffer-undo-list special-point-history))
  <... move point>)

Then, one can hack on existing packages like vundo to get the tree-like
interface.

I am not sure if it would be something we need in Org mode though.
Maybe ELPA package or something.
