My impression, is that most of the techs at the local dealership are working on several bikes at a time, all at different stages of repair. Either waiting on a H-D rep to approve a warranty issue, waiting on parts for one, etc.
That as a result of not starting and then completing a repair without interuption, they are simply missing steps along the way. Like, not putting any fluid in the primary (had that happen), leaving the spark plugs only finger tight (had that happen), leaving the engine oil two quarts low (had that happen too). Obviously they did not intend to send it out with these problems, least I hope so.
It could easily happen doing multiple bikes as I have missed steps doing my own work but figured it out prior to finishing and had to go back.
