I like that they speak of variations.
Shouldn't WhatsApp have picked 255?
Doesn't the question why they picked 256 number make you even more worried if you you understand the significance 😳?
I assume it is not actually about the chat itself, but about the double ratchet group key management. It organizes keys in a binary tree, and adding or removing users involves rolling over a key on each level of the tree. 256 means the tree has 9 levels. So, the "oddly specific" number here is 9, and that in turn probably is "just one more than before".
