Yes & it doesn’t work very well. Or at least it didn‘t,

Apple has been notorious for sacrificing good strain relief on their cables in pursuit of aesthetics for years. Possibly things have improved now that Ive has left, but there was a period a few years ago when everyone I knew with a Macbook had wrapped the power cable in electrical tape because the cable housing had failed just above the (useless) strain relief sleeve you describe.

I think it was less the strain relief and more the rubber they used. It would go gummy and fall apart after a few years. I absolutely remember around 2013 everyones MacBook charger would fail like this.

But they have changed the design a lot since then so I no longer think this is an issue. The brick is now usb c so you can swap the cable without needing an expensive brick, and the MagSafe cables they now include are braided instead of rubber.

The USB-C charging cable from the 2020 M1 Macbook still has the issue of straining just after the strain relief. It's not a good cable. The only good thing about it is that is a standard cable and you can replace it with a more reliable one.

Whether the cables with the braided sleeve are better is something that remains to be seen.

I had the same with my previous MBP, I had the machine for ten years and had to purchase two new power bricks along the way. Thankfully the new cables are nicely braided and replaceable without buying an entire new brick.
