it is very common that guitar bodies are made from several blocks of wood ~4-8" wide glued together on the edges. most bodies are at least two pieces, and some can be as many as 4, like my RG2027. the 1527 body is almost certainly at least two pieces of edge joined wood, and possibly 3 or 4.
"laminated" refers to flat layers [i.e. 'lamellar,' etc.], like plywood, not edge-joined blocks of solid wood. only really cheap guitars will use plywood for a body -- even the recent Squiers are made with solid agathis rather than plywood.
there's no way a mid-high end RG is made of plywood. you might be seeing the edges of router cuts or coats of shielding paint that can look like a layer in the wood underneath.
