Grootslang and multiple Terrain markers

[Domin]

Maybe it can sound stupid, but I wanna check:

Grootslang's Wall Climber Ability says that while he is in base contact with a Marker that counts as Terrain, he gains positive to all non-damage flips. If he is in base contact with Lair marker, he also deals +1 damage.

So the question is - what if he is in base contact with two terrain markers or two Lair markers - shall the bonus double or not?

No, the ability just gives a yes/no conditional statement, and that condition is fulfilled then a buff is applied.

I don't think it would double, it's more of a "are you or are you not in contact with such a marker" kind of statement.

If anything certain people would argue that if you are touching two markers you don't fulfill the condition since you aren't in contact with "a marker" but two markers. I think this argument isn't correct.
