Right, asymmetric paths are the norm for many inter-provider communications. A related misconception is that asymmetric paths are problematic. Another mis-conception related to path is that more (visible) hops are bad with the corollary that routers introduce (significant) latency. Of course, propagation delay is the most significant contributor to latency in WAN environments (or serialization delay for low-speed links).

Or more to the point, it is a misconception that traffic is symetrical (the path out and the path back are the same) whereas in the present network, symetrical paths are the exception rather than the rule, especially as your radius increases.

traceroute shows _a_ path. Your packets might have taken a different path. (& the return traffic yet another)
