I suggest the letter is specifically for the Spain branch. On reddit there is a clearer screenshot of it and it mentions a couple of specific banks CaixaBank and Banco Santandor, as well as the datestamp:
If there has been a similar letter in the US, I haven't heard of it. However, it is likely such a move would be played out for all branches in time.
What I find incredible is that the branch would be taking on the mundane task of paying all the bills for a KH. Any payment, however small, would have to go through the branch software. That's thousands of silly payments of routine expenditures. Such a bureaucratic nightmare that I can't envision it working.
