why can't it be the other way round?

Usually, in a blood transfusion they use "packed" red blood cells. or blood where white blood cells and other material (plasma) are removed. there are no antibodies to go into the recipient.
now if they do a whole blood transfusion, there are some antibodies that enter the recipient, but it requires the body's lymph nodes and the bone marrow that produce more antibodies that cause problems.
when a donor's blood enters a recipient has has markers called "antigens" (if it's not matched right). the recipients antibodies attack the antigen, and cause fever and anemia. you also can die from this.

Hypersensitivity/allergic reactions only happen when the recipients antibodies recognize a foreign antigen. So if the antigen of the donor doesn't match that of the recipient and the recipient has antibodies against that antigen you can have a sever allergic reaction. your not concerned with the donor antibodies for this scenario because they will not be able to stimulate the recipients immune system to trigger the allergic reaction.

they the two might desire to be seen- if the antigens are in comparison to minded with the host's immune device, the immune device will react to the blood, rejecting it that's rather undesirable because of the fact the host is in all probability not interior the final shape already besides
