My understanding is that these restrictions were only imposed in December of last year (and are in force until at least 30 June), so I would tend to agree with the parent that they definitely changed directions.
They added some restrictions, certainly, but it's completely inaccurate to suggest that they've somehow reversed course -- the OP is erecting an ideologically rigid, straw-man argument that Sweden can never do anything differently at all, or they are somehow "going back on" their initial approach.
Overall, Sweden has taken a light touch with the pandemic, and continues to do so, even though, yes, they've adapted over time.
Of course they went back on their initial approach, same as the UK. If you say "no need to restrict anything, it will go away", your death toll is significantly hire than comparable countries, and then you enact restrictions, what is that? Yes, the situation and our knowledge of the virus and the pandemic is highly evolving and the UK took barely a few months before making a U-turn, while Sweden persisted for many months with their strategy, in spite of the death toll, and some research saying that the economic impact is still significant.
