That's because the let-binding was in a buffer which had a buffer-local
value, so the let-binding only affects the buffer-local value.

    (defun get-A ()
      (with-current-buffer "A" myvar))
    (defun get-B ()
      (with-current-buffer "B" myvar))

    (defun get-test ()
      (setq myvar 'global)
      (with-current-buffer (get-buffer-create "A")
        (setq-local myvar 'local-A))
      (with-current-buffer (get-buffer-create "B")
        (setq-local myvar 'local-B))
      (list (list (get-A) (get-B) (default-value 'myvar))
            (with-current-buffer "*scratch*"
              (let ((myvar 'let-bound))
                (list (get-A) (get-B) (default-value 'myvar))))
            (with-current-buffer "A"
              (let ((myvar 'let-bound))
                (list (get-A) (get-B) (default-value 'myvar))))
            (with-current-buffer "B"
              (let ((myvar 'let-bound))
                (list (get-A) (get-B) (default-value 'myvar))))))
