Относно: looping around

In a book about games I found this cylinder chess problem:
-------------
White: Ra5, ph6, Kc3
Black: Kb1, pa6, ph7
White to play, mate in 2
-------------
The proposed solution is
1.Ra5-a5! Kb1-c1
2.Ra5-a1++

I haven't tested if this move is possible here at BK yet. My feeling is that it isn't... Truth be told the rules don't exclude the possibility that a Rook (or a Queen for that matter) loops around the board to finish the move in the same position it started in.
Nowhere on the web where I found rules for cylinder chess is this option discarded (nor noted) either.

What do you all think? And if it isn't possible in BK, should it be?
