The doc string of 'repeat' says:

  Repeat most recently executed command.
  If REPEAT-ARG is non-nil (interactively, with a prefix argument),
  supply a prefix argument to that command.

So "C-u 98 M-x repeat" invokes the _previous_ command, in your case
C-y, with the argument of 98.  And the documentation of C-y says:

  With argument N, reinsert the Nth most recent kill.

So it does NOT insert the most recent kill 98 times, it inserts the
98th recent kill.

Does this explain what you saw?  If not, what remains unexplained or
unexpected?

Thanks.
