Does "Patching Bus IDs" document have a bug? I am very confused.

I am reading https://dortania.github.io/OpenCore-Post-Install/gpu-patching/intel-patching/busid.html#parsing-the-framebuffer

​

It has the following words:

​

So since entry 2 is the second in the list, we'll want to use con1:

framebuffer-con2-enable

And finally, we're given the following patches:

framebuffer-patch-enable | Data | 01000000

framebuffer-con2-enable | Data | 01000000

framebuffer-con2-alldata | Data | 01050A00 00080000 87010000

​

I am very confused. it says we want to use `con1`, but all the following contexts are using `con2`. WHAT? Do I misunderstand anything?
