See timer-event-handler, which is the function invoked when a timer is
ripe, and handles both the invocation of the timer function and
rescheduling of the next timer invocation. My reading of it is that
the above _could_ happen, but:
. it can only happen if the timer function calls something that
causes Emacs to wait for input, like sit-for, perhaps or
accept-process-output, because otherwise Emacs will not check for
ripe timers for as long as the timer function runs
. the number of such "overlapping" invocations should not be more
than 10, controlled by the value of timer-max-repeats
