Actually `M-e DEL RET' is not equivalent to `DEL'.
It is equivalent to `C-M-w' (`isearch-del-char').

`M-e DEL r RET' is not equivalent to `DEL r'.
It is equivalent to `C-M-w r'.

WRT automatic changing of case-sensitivity after entering
an upper-case letter, this is a traditional behavior that
you can disable by customizing `search-upper-case' to nil.

This is unrelated to `isearch-edit-string'.  You'll get the same result
when you type `C-a C-s b u f f e R C-M-w r'.
