I don't see why a grass snake would spot this danger sooner. It just might flee sooner.

I might be wrong but I think their eye sight is much better than in adders.

Why?

The question of snakes basking together reminds me of the much discussed question why V. ammodytes climb
the branches of trees and shrubs - quite regularly - (and V. berus don't.) There have been some explanations
offered, like (1) much easier thermoregulation than on the ground, (2) hunting birds, (3) both at the same
time, (4) hunting rodents foraging for fruits (which could/should explain why they do it mostly in late summer
and early autumn), (5) you name it...
Noone has ever offered any explanation why V. berus wouldn't do the same for exactly the same reasons...

I'm afraid, one should ask the snakes themselves, but they are not likely at all to oblige us with an answer...

On my lowland bosniensis cmr site i regulary observe balkan adders basking on low shrubs (30-40cm), last year in early spring we observed one male basking on a small tree at a little bit higher then 60cm.

... and some more thoughts, why ground dwelling snakes (here Crotalus cerastes) climb into bushes.

Interesting! Do you have any photos of that?
