The author explained his motivation for the commit in the mailing list before 
it got applied:

If I understand correctly, executing a lob call would trigger two user 
confirmations in the past, and this commit was meant to suppress one of the two 
confirmations. (I may be wrong since I am a fairly new user of org mode.) Now 
there is no confirmation at all. IMHO, there should be exactly one confirmation 

But you are right, I should just copy the author on this.
