Yes, that does make sense. However, I think it would be silly of them to let Sims wear slippers in the game but have to use props to leave them about the house. Someone did actually say that putting shoes on and taking them off was confirmed, but obviously this might not be the case. But I see what you mean, and you may be right. But I have just squinted a look at the slippers beside the daughter's bed, and they do look a little different to the ones in the parent's room. Who knows? :-\
