You are correct. "as" is generally used when something is similar.
"As I told you before, the car is too old". What I am telling you now is similar to what I said in the past.

"This car is as old as your son". The age of both are similar.

"As we have spoken about this in the past, I see no reason to continue, as the story is the same".
The current discussion is similar to one we had in the past. The story now is similar to the one before.
