remove old siding before installing new?

Needing one side of my house resided. It currently has two layers of siding -- the original masonite (I think it's called) siding plus some T1-11 plywood siding on top of it. I noticed some wood rot where the horizontal trim boards cover the seam between the 4X9 sheets.

Am currently getting estimates. A couple contractors said they could put new siding on top of the current two without any issues. Three said I definitely should replace one or both of the present layers.

So what should I do? Cost looks to be double to remove and replace rather than just put on another layer. I should add that sq ft of wood rot area is not huge - probably 1-2 sq ft. On one hand, removing it all feels like the right thing to do. On the other, I don't really see a logical reason since the area of wood rot is small.

Thanks,

Ken
