i dont understand.. what exactly the question was?

Sometimes, based on their hairstyle, expression, etc.
In that pic, YES. (￣▽￣)

found another twin couple yuri and seohyun

Yes they can sometimes depending on what their hairstyle is now that Taeyeon's hair is lighter I think they are starting to look plus similar. I used to get them mixed up a lot.
