Yes, it gets complicated quickly.
I wrote one byte to vbmeta_system_a and _b each.
It bricked. I compared using something that I had just written.
There was a ton of stuff that had changed, but ignoring userdata:

The first column is the partition name.
The second is block number (quantized to 1MB or 2048 x 512 bytes).
The third is the number of bytes changed in that 1MB.
