a = new THREE.PlaneBufferGeometry( 1, 1, 2 )
b = new THREE.PlaneBufferGeometry( 1, 1, 2 )
console.log( a.attributes.position.array.length )
a.merge( b )
console.log( a.attributes.position.array.length )

Yes. The method does not support indexed buffer geometries. Also buffer geometries can’t be resized. Have a look at the source code so you understand what the method’s limitations are.
Quite frankly, I can see a compelling argument for removing the method altogether — or perhaps substituting a utility like:
which would merge multiple geometries at once, rather than incrementally. But even that method would have significant limitations.
