Yes, the masks are used mainly to reduce your spreading to others. Not so much to protect yourself.

Judging by that quote, some people don't seem to know this, and you can bet they act like it protects them more than it does.

  Point is infected people can be asymptomatic and wearing masks will reduce the chances of them spreading it to others.

Although many masks have a one-way valve or vent which allows exhaled air to bypass the filter and infect others.

  N95 masks in particular.

    But someone who regularly wears an N95 mask with a valve might be less likely to contract the virus (because N95), so discouraging use of N95 masks with valves could make the situation worse.

      N95s are good for protecting the wearer, not so good for protecting others from the wearer. In areas with high infection rates (a lot of the US), the likelihood that someone wearing a mask is infected goes up, thereby making N95s more problematic. Many stores around where I live are requiring N95 wearers to cover up the valves while inside. N95s are better than no mask at all of course, but that's a low bar for comparison.

  Even self-made cloth mask show an effect on reducing spread. More and more studies show this now - and you can try for yourself. Put flour in front of you in cough into it, once with a self made mask and once without. The spread will be much less. Surgical and N95 masks are better to protect yourself (and others) though. Still, even a small reduction in spread can have a huge effect on the pandemic if everyone adopts it. https://advances.sciencemag.org/content/early/2020/08/07/sciadv.abd3083.full https://advances.sciencemag.org/content/early/2020/08/07/sci... https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7321045/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7321045/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7186508/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7186508/ https://jamanetwork.com/journals/jamainternalmedicine/fullarticle/2769443 https://jamanetwork.com/journals/jamainternalmedicine/fullar... https://pubs.acs.org/doi/10.1021/acsnano.0c03252 https://pubs.acs.org/doi/10.1021/acsnano.0c03252 https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7191274/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7191274/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7253999/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7253999/

Although there is a body of evidence building that you are more likely to have a milder case if catching it wearing a mask (due to a slightly lower initial viral load). https://www.ucsf.edu/news/2020/07/418181/one-more-reason-wear-mask-youll-get-less-sick-covid-19 https://www.ucsf.edu/news/2020/07/418181/one-more-reason-wea...

I'm reading it as he went to a place were nobody wore mask, thus increasing the spreading. He's not saying that he took his mask off for a brief moment so he caught it, but that everybody put their masks away for the entire evening.
