This is interesting.

How did you measure the caffeine content in the capsule? Also, I assume that is the total amount of caffeine present in the capsule, and not the caffeine dissolved in a cup of coffee (since that would depend on the amount of water running through it, and possibly on temperature and mineral contents as well.)

I believe that Nespresso measures the amount of caffeine in the final drink, assuming you used the correct serving size. For example, for Ispirazione Napoli (https://www.nespresso.com/tw/en/order/capsules/original/ispi...), they claim that "Per serving of Caffeine is 109mg/25ml".
