As I read that, "more than a screwdriver" was to make a point about how hard it is to even fulfill the requirements for "assembled in the USA". "Made in the USA" is even stricter. And they were going beyond that and claiming secure supply chains with western distribution. It did seem a little like a marketing pitch since it focused on what they did versus what the final gap really was, but apparently they sell it to the govt for that big markup. Presumably you don't want to try and sneak things past such a customer.

If you're just thinking of price, the farther down the supply chain you go the less impact of tariffs.
