^The line also sets up the fatal transporter malfunction that occurs shortly after. The problem is, even if this is what the intent of the line is, we are left with the problem that everything we know about transporter technology as of that film suggests that Enterprise's transporters not working shouldn't prevent Kirk from beaming aboard. Starfleet must have a few dozen working transporters at least, and even if for some reason the ground transporters couldn't beam him up to a ship, the transporter room on the Orbital Complex certainly should.
Ultimately what we have here is screenwriter intent going against common sense logic of the situation. We each have to choose our own way to reconcile. I personally prefer to go with what is visually depicted over screenwriter intent in this case. Hence, I like the suggestion that Kirk is really there to meet Scotty.
