That article is extremely alarmist. I have Maxell, Fuji, TDK and Sony cassettes that have been in my possession for over 30 years, with recordings on them that sound like the day I made them. And some of those tapes have been recorded over multiple times.
As long as you have a good deck, and keep your tapes in a dry, climate controlled environment.... don't worry. You should be able to re-use that tape over and over again. One exception might me if you record a very hot signal (levels too high) onto a Metal bias tape, there may be some lingering "print-through" that is the result of the erase head not being able to fully erase the tape prior to the new music being recorded on top of it. You might hear some of what used to be on the tape during quiet passages or between songs. But, for normal or chrome bias tapes, there is no set limit that I know of as to how many times you can record over and over again on the same tape before you notice a drop in performance.
Sticky Shed Syndrome is MUCH more of an issue for open reel tapes than for compact cassettes.
I am an active participant on another forum dedicated to tape recording (
http://www.tapeheads.net) and have done some extensive reading on this issue, not to mention my own personal experiences. I have had open reel tape disintegrate on me and make a mess of up the heads and transport on my R2R, but it was tape from the '70's and I have no idea how it was stored. Considering I'm in Florida and that tape came from a flea market, my bet is that it was literally in someones non-air conditioned shed.
Cassettes that I've heard about (on tapeheads) which have developed SSS were stored in damp environments for prolonged periods or were limited to specific production batches where the hypothesis is that the chemical formula was probably not 100% correct.
I still buy quality used tapes from thrift stores because most the "good" tape models and formulations haven't been made for upwards of 20 years now... And I record on them regularly with stellar results.
