It was just an idea...
There are several major products that are Kosher or Halal despite the biggest market being the West. Snapple Ice Tea is a good example of a Kosher product.
The only rationale I can think of is if you are going to mass produce some food product, better to start with something you can sell everywhere, than start with a Western version and then change (or add to) your product line later.
There are a lot of products that are by default Kosher and Halal and just added the sticker on top for advertising. What could you add to Ice Tea to make it not kosher other than preparing it in non-kosher equipment (which is possible, but unlikely in the case of ice tea)
