To be precise, A is requesting to pay money to B.
My main issue with a negative total is that this is incompatible with most (if not all) cryptocurrency payment methods, without reissuing the payment request in the opposite direction with a positive amount. This is because, for example, a basic bitcoin payment request might be represented as
{amount, currency unit, address}
A payment can be made **to** that address but it cannot come **from** that address. See https://en.bitcoin.it/wiki/From_address
