What is the point of setting Haveno limit on maximum traded amount per payment method?

At https://docs.haveno.exchange/the-project/payment_methods/0-all-methods/#2-altcoin-payment-methods I can not find any explanation why the limit is placed, i assume that it limits the loss per trade, but then the scammer can do multiple trades and the loss is the same? So what is the point? If it is not like that, then please explain or link me to an explanation? Thank you
