Scuffers :
I can see how mistakes can happen
No you don't.
, I'm amazed anybody can understand that real-time.
Well as said before , this is likely from a hand held scanner , the ATC real R/T quality is generally much better but not always ( thinking more HF) , no generally mistakes like this do not happen because of quality , if you have a doubt , we ask to " say again" . Here the instruction to line up and wait was repeated by the PNF, so understood. No complied with by PF is the issue here.
