That is true for most every style V8. The reason the cam timing is done dot to dot is because it's much easier to get them aligned when they are closer together such as the 6 o'clock/12 o'clock orientation. Imagine how many times you would have to install/reinstall the timing sets to get it perfectly aligned if you used the 12 o'clock/12 o'clock orientation. Most people don't realize that the dots on the timing set end up at 12 o'clock/12 o'clock to correctly install the distributor because the timing cover is already installed. Yes it can be confusing, but as has been mentioned and confirmed by several others, it really is two separate and different procedures, but are often confused as being one in the same.
