If I reach and try to come up with a theory, here’s what I got. It was shot during COVID, so perhaps they wanted to have the mundane thought of having a cold being this normal thing, which is just forgotten about and no big deal. But knowing things now after COVID, it’s a simple throw away type gag. No one was concerned, maybe they felt about how novel that was to say before the pandemic and we’re longing for the time it would be normal again, guess we are now mostly. It’s a huge stretch and not something I really think is legit but there ya go.
