Interesting debate how a Vulcan V-twin is different than a HD V-twin

The classic Harley-Davidson engines are V-twin engines, each with a 45° angle between the cylinders. The crankshaft has a single pin, and both pistons are connected to this pin through their connecting rods.[9]

This 45° angle is covered under several United States patents and is an engineering tradeoff that allows a large, high-torque engine in a relatively small space. It causes the cylinders to fire at uneven intervals and produces the choppy "potato-potato" sound so strongly linked to the Harley-Davidson brand.

To simplify the engine and reduce costs, the V-twin ignition was designed to operate with a single set of points and no distributor. This is known as a dual fire ignition system, causing both spark plugs to fire regardless of which cylinder was on its compression stroke, with the other spark plug firing on its cylinder's exhaust stroke, effectively "wasting a spark". The exhaust note is basically a throaty growling sound with some popping. The 45° design of the engine thus creates a plug firing sequencing as such: The first cylinder fires, the second (rear) cylinder fires 315° later, then there is a 405° gap until the first cylinder fires again, giving the engine its unique sound.[102]

But correct me if I'm wrong isn't the Vulcan V-twin basically the same engine configuration? Single pin crankshaft. "Wasted" spark system. very close to 45 degree V angle (I think the Vulcan engine is something like 46 degrees??). Seems to me the Vulcan engine would have the same plug firing sequence with a slight difference due to the angle "V" being a little more than HD.
