Well, yes, that's part of my point. You know "Segway" but not "segue". Speaker says "segue", because they're close homophones and you don't know "segue", you parse that as "Segway". But the problem is, the resulting sentence doesn't make any sense. At this point, you either look it up to make sense of it and discover "segue", or you're OK saying things that don't make sense if they sound cool, and start using "Segway".
