what's the point of the Merge shader that goes nowhere?
something borrowed,
something Blue.

What do you want to achieve with this? The masking follows the contours of the terrain allright (though I stretched the Y of the terrain to 10000, which allows for better masking).

i want apply the mash with shape of contour to a flat plane.

It's better to use the colors/scalars from altitude to make your contours. Altitude itself doesn't work like this. See screendump. The color adjust shaders (or smooth step+ 2 constants) give you some altitude, which you can add and subtract, etc, until you have the desired contours.
