Parts substitution or mistake?

I recently submitted an order with Courtesy for the essentials for the timing belt job. I used the part numbers referenced on Zenon's page, which includes the CHTS and subharness. Somewhere else I read a recommendation to replace the coolant temp sensor as well while doing this job. The part number for the CHTS and coolant temp sensor are similar, with the coolant sensor having an R at the end of it. They have different suffixes (01P01 for the CHTS and Z31001 for the coolant temp) on the order confirmation, so I assumed I was going to receive two different items. When I received them, however, they appear to have sent identical parts. The packing list shows that both are 22630-01P01, even thought they have different product descriptions.

I haven't gotten to these in the disassembly yet, so I may answer the question myself shortly. Just wondered if this is correct, or did I misread something?
