A very good observation Op I think it takes someone who has made this particular mistake to understand the importance of double checking your seed phrase even after writing it down for proper confirmation. The last time I made this mistake was the day I tried to screenshot the words so that I can write them down when am less busy but guess what, it was unable to screenshot and out of curiosity I almost made the mistake but thank God I checked it again if not i would have ended up making this mistake so kudos to op for bringing this up here.
