What makes blood subs in rugby significant, and why it's an issue here, is that the bleeding player can be replaced by a fresh sub from the bench and then re-enter the game once they are cleaned up. It can be a pretty big advantage to have a fresh guy on the field or have an important player get a few minutes of rest without the sub being permanent, as any other sub is.
I'm 99% certain that there is no such thing as a blood substitution in soccer, at least not at the professional level. The team with the bleeding player either plays down a man until the guy is cleaned up or they make a sub that is permanent.
