You didn't read the account very carefully at all, did you?

They never said the stems were soft and mushy, they said the leaves were
dropping and the stem segments disarticulating.

Those are signs of malathion poisoning not over watering, you clown. The
poisoned joints will not root and the plant will eventually die no matter
what you do. The plant's metabolism has been completely screwed up by a
chemical poison and the condition is not reversible.

And, what if the owner says he/she has had the plant for a number of years,
and has never applied any chemicals to it? Got another theory ready?
