No, they're not used in different places, not really.

I know some people use {} for one-liners and do/end for
multiple-liners, but sometimes it is important to use one over the
other because of the binding precedence.

  foo bar {} # the block binds with bar
  foo bar do end # the block binds with foo

If you're going to have it for do/end, you need it for {}, too.
