Unfortunately bike packing seems to be a crap shoot. I have taken to only buying from people that I know can pack a bike. I had one that was "professionally" packed, all they did was take the major components off, tape them to the frame with packing tape, dump the bike in a box and fill it with Styrofoam peanuts.
Unfortunately Ooops dropped the box and the rear dropouts were folded over at a 90 degree angle!
Given the value of the bike it was not worth hassling over, but the seller only got a neutral feedback.
And in answer to the OP, no that is not an acceptable packing job, in fact it looks like the person was pure lazy.
