Distancing Not Required?

The high vantage angle overlooking the swimming pool underneath from the window at the condo that I am staying is as good as using drone. I was attracted by the vibrant colour of the pool and the swimmers. Before the Covid 19 measures tightened ahead from 26 Jan 2021, it is better to have a game of water polo. Is distancing of 1M apart not required in the pool? I wonder? (image captured on 23rd Jan 2021)
