It's the same reveal as in ANH. Desert place looking for someone. Some guy comes around and is asked: "Hey do you know *****". "Yes it's me".
No it's not. With Yoda, there's a period of "oh this little green guy is going to take me to Yoda later". They're pretty different!
And I say that as someone who thinks preserving the Yoda surprise is dumb.
