I don't think that's right at all. Rather the idea is that, if you fix them
both at once (ie do a full rebuild), then it will maximize the time before
something fails again. I've fixed just one or the other several times, and
never seen any indication that it accelerated any other failure.

Guess it depends on your point of view. If you just can't think of anything
else to spend your time and money on, then doing a complete rebuild probably
makes sense. Of course, now that you've got the engine out, it only makes sense
to do a full frame-off restoration of the rest of the car too...
