I don't know what this does, nor why it seems to bind both "\C-i" and
[(tab)].

So, you don't care which command was run, but instead you want to
delegate to the other command which would be run if you ignore the
"currently used" binding.  This is a common need, of course.  With many
different solutions, none of them perfect:
- Use a menu-item binding with a :filter so the binding can be computed
  dynamically (i.e. it's bound to org-cycle if point is on a heading,
  and to nil otherwise).
- lookup with (key-binding (this-command-keys)) disabling your own
  key-binding (easy if it's on a minor-mode map or something similar).
  Usually (this-command-keys) does work, tho you claim it doesn't for
  you (still waiting for details on this problem).
- lookup (key-binding <some-hard-coded-key>).
- use a hard-coded fallback command.
- disable your binding, then push this-command-raw-keys back on
  unread-command-events, while arranging to re-enable the binding
  after the next command.
