Old question, but attempt to an answer by a new member. I can't comment on the varieties mentioned specifically, but have seen similar things happening.
Apart from all the answers provided, I believe it has to do with the taste too. For many (Indian) recipes there is a distinct ask or demand because of taste variation. A green pepper tastes different than red pepper than dried red pepper than crushed pepper.
I have heard about few recipes where it asks for green and (wet/not dried) red peppers because of taste variations.
From personal observations, green pepper taste and texture is definitely different than red, not yet dried, pepper. To me red, not dried pepper tastes somewhat sweeter even though I would find the green one of same verity somewhat hotter.
