OK. What you'd *like* is for the subject to change and the thread to be
cut when the topic drifts. This also assumes that the topic drifts in
one post -- this isn't a given. And that poster should always change the
subject and cut the thread.
Good luck!
In practice, this *doesn't* often happen -- even when you have "net
police" reminding people to change subjects.

Only if one could have the existing posts on the drifted topic in the
new thread. That's not technically possible.

Then yes, if you come across the new thread before the original thread,
you can find what the original thread was.
If someone comes across the *old* thread first, not only will they be
unaware of the new thread, they may well contribute a new response to
the old thread saying substantially the same things as the first post in
the new thread, but *still* forgetting to change the subject -- or
changing it to something else!

Good example. That one might go via "cleaning methods", "what sort of
chemicals can you use to clean certain types of car paint", "you
wouldn't want to use X on a car -- it's OK for cleaning ovens" and "you
should *never* use X on an oven!"
Assuming both subjects are on-topic for the forum, some of the
intermediate posts are at the same time part of *both* topics. And you
can't cut the thread at "you should *never* use X on an oven!" without
removing it from context and risking readers just seeing "X is OK for
cleaning ovens" and ruining their oven...
And if the poster of "you should *never* use X on an oven!" forgets to
change the subject, you're likely to have several responses, some with
different subjects, and some in different threads. That's not ideal,
either.
Or we could look at this example. I've changed the subject of the
thread, because it's drifted. But it's a close response to yours, and
belongs with yours. I can't go back and change the subject of your post,
or of my previous one.
