This isn't even enough: you should check if the seed creates the same address again.
Why though?
I would never even try to copy an Address from a Seed that I have not backed up properly. To me the verification part of my paper is part of a proper backup. Since the Seed will not be used at all before I restore, the worst thing that could go wrong is I wrote an invalid Seed in which case I have to redo the entire process or I just restored a valid Seed that I some how managed to mistakenly create by my own mistype.
Is there a risk I am missing on? I suppose it is that you are afraid the mistype will significantly reduce the security of the Seed?
(of course running offline, air-gapped, running a Live Linux DVD from RAM, with the curtains closed on a computer that I'll burn in holy fire afterwards)
You are taking the definition of extreme paranoia to a completely different level. Not that I do not like it though, the more precaution the fewer the worries.
