Le sigh... I'll continue to post references... And no, it doesn't go without saying because no one can verify in the source.
Here's the first REV2 release for mainnet. Note it says "decentralised trustless mixing", not multipath.
Do you seriously need Dan to come here and say that XC has multipath? I've just told you it does. What more do you want?
If Dan says it you still won't have access to the source code to how will this help you?
Furthermore you can make a private payment and then watch the fragments going out on any block explorer. That's multipath.
