I think you misunderstand the meaning of global.  "Global" here means
"affects all buffers" as opposed to "local to a particular buffer".
I guess they could both be buffer-local or bother be global, but having
one be global and the other buffer local makes no sense.

It was a typo for mvi-insert-mode.

Better make it into a proper minor mode (rather than a weird beast
which doesn't do anything when you turn it off and turns itself off
when you turn it on).

(define-minor-mode mvi-mode
  "Minimalistic VI-like mode."
  :global t
  (if mvi-mode
      (or mvi-insert-mode mvi-command-mode
    (mvi-command-mode -1)
    (mvi-insert-mode -1)))
