Still, the elevation of the RWY being in its centre (as claimed by D
Ramapriya) still denies any logic as far as I can see.

If the high point is in the middle, it's probably because that's what
the terrain looked like before the runway was built. Ground never comes
perfectly level, and it's often not worth the expense of fixing it to be
absolutely level just because you happen to be building a runway.
