It is interesting that you bring that up. Ironically, from Luther's Baptismal Booklet:
The baptizer shall say:
“Depart, you unclean spirit, and make room for the Holy Spirit.”
Then he shall make the sign of the cross on both the forehead and the breast and say:
“Receive the sign of the holy cross upon the forehead and the breast.
“Let us pray.
“O almighty and eternal God..."

Therein, the sign of the cross is an exorcism, no? So when was the statement "to mark you as one redeemed by Christ the crucified" added and why? (There's a master's thesis topic for someone. Or maybe it's been done. I'd appreciate any citations anyone might have.) The addition of the statement seems to change the character from an exorcism to a statement of what is being done in baptism. As you correctly observe, temporally we can't do everything at once.
I certainly have no problem with the statement and action, for it extols baptism, and it is part of the rite just as is placing one's hand upon the child and speaking the Prayer of the Church- the Lord's Prayer- prior to the actual baptism.
The exorcisms, however, tend to confuse as I stated above. In my opinion, they do not extol baptism, which is the only "exorcism" needed. For baptism rescues from the devil, where the Holy Spirit enters unclean spirits must flee, and the Holy Spirit might be a gentleman, but He goes wherever He wishes.

In baptism, the Lord puts His name on us and proclaims, "Not this one, Satan! This one is mine!"
Oh wait, I think I've heard you say that...
