yes a very bad notation system in my opinion :(
F.i.
C8f5 R9h8
Would mean:
Cannon on the 8th file counting from the right seen from reds point of view goes forward five 'squares' - Rook on the ninth file counting from the right seen from of BLUE's point of view goes horizontally to the 8th file

Moving a forward/backward 5... then I have to count to see where it lands!
When you missed a move in replaying, you can't see directly where you made the mistake.
Also it's very tiring to constantly switch to the other point of view. (This is the ninth file... oh no, it's the first!)

So to me it's a disaster.
