As the original movie from the Year '73. contains two other park for the guests, it was not unusually to see the actual SW logo referring there is at least one more park called Samurai World. We do actually see the scenes where the two Samurai are fighting. As Maeve act surprised by seeing those characters so was i. It can mean there're many different types of parks but not collaborate or interfere with the Westworld story. I found this highly amusing as well as quite logical. Here's the real meaning how huge the park really is but our story is happening in the Westworld park and there's no need to go out of there. It was simply enough to show us with the SW logo and Samurai scenes there is a lot more than meets the eye referring to other parks with androids as their inhabitants.
