Dial Watch, ISDN not going down

Is there any requirement that the watched router has to be in the same area
as the ISDN link ? How does dial watch know that it is the right route that
is back ?

            R1 ----- area 0 ISDN -----R2----|
            | | LAN area 2
            |------- area 0 frame--------R3-x-|

r2 watch lo0 on R3. Shut down eth0 on R3. R2 loses watched route. Brings up
ISDN. Gets watched route via ISDN and area 0.
When eth0 on R3 is restored. R2 does not prefer the route from area 2 and
ISDN stays up.
If I put all links/routers in area 0 is works, ISDN goes down when watch
route is restored.
Is this normal ? or did I make an unsupported network topology ?
