No, this was a new study from South Korea. Really just looking at antibody levels over time and demonstrated that for most people the levels started to fade after a few months.
Those people who had mild or even no symptoms while being COVID positive saw their antibody levels fall more quickly.
1. Doesn’t mean that people would be reinfected, but certainly could, especially given what we know of other coronaviruses.
2. Says nothing of possible T cell mediated immunity.

Is this it? Looks like it is out of China.
Definitely no reason to truly panic based on these results, as that is only one level of our immune system, especially considering the data involving T-cells.

I mean isn't this to be expected? Does anyone expect our immune system to have antibodies floating around for stuff we beat 20 years ago? Our immune system thwarts virus and bacteria all day, every day.
You can take an agar plate, swish it around in the room you are in right now, close it up, throw it in an incubator, come back two days later and it will be growing all kinds of stuff.
I read a paper earlier this year about how people who beat SARS v1, didn't have antibodies, but still had some form of immunity 15 years later. On my phone and don't feel like searching for the paper right now.
ETA: paper from 2017 > T-cell immunity of SARS-CoV: Implications for vaccine development against MERS-CoV
