They are slurs (the ones made with parentheses). Slurs and ties look
the same, but musically and logically they are quite different.

Yes, i think that there should be a natural (perhaps parenthesized)
here - to make sure that noone mistakes this slur for a tie.

No, here you are not right in my opinion. There is simply no reason to
put a slur here, you should write aes'~ aes' and not bother with ( ).
