A webpage of the Australian Department of Environment & Heritage National
gives this advice:
"Plants in containers perform better when root-bound and should not be
transferred to a too-large pot when re-potting. The use of terracotta pots
provides a simple method of repotting. The pot can be cracked all over
with a hammer and the plant with its cracked container can be repotted
into a larger pot lined with fresh soil mix. This allows the roots to
penetrate into the new mix while the root system is held firmly together
by the cracked pot."
I've never heard of this method of repotting without removing the prevous
pot. Cracking an otherwise intact pot does not strike me as much of a
guarantee that roots could easily get through the barrier to the next zone
of soil. Nor have I ever noticed a problem of rootbound plants coming
apart by being removed from pots. It has been my experience that roots
SHOULD be broken up a bit around the edges when rootbound. It just seems
like loony advice. Has anyone ever heard of this repotting without
removing the old pot before?

Oh yeah that's because I'm in Australia!
I've never heard of this cracked pot thing, but I have heard that Hoyas
prefer to be rootbound, especially if there is trouble with flowering. I
always assumed it was because in their natural habitat, the soil was much
firmer. I dunno though. I'm sure it wasn't actually an Australian book
I agree that this is a antithetical method of repotting. Root bound
plants can be tapped out of their pots. I run a knife through the
roots and repot into a good 1-1-1 mix. Soil, peat and perlite.

Your link is advice from 1986 for growing a Hoya in Australia. Aside from
being good advice for fast-growing root climbers (whatever that means),
it's good advice in general, because being root bound Down Under helps keep
the plant in the pot. Otherwise, the plant would fall and fly out into
space and quite possibly cause a mass extinction in some other solar
system. In fact if you break into a certain Defense Department computer
and read some of the classified SETI transcripts, the second most common
intercept from Rigel Kentaurus is 'ipso zeebop maxturd treblesmurf
blunderwipen' or roughly translated 'oh maxturd, some moron repotted
