This is very common for small orgs where communication is already daily or the matter is trivial in the first place. The reason minutes are signed at all in such cases is to have a paper trail of the decisions and a date for the meeting held, as that might be a legal requirement.
As an example in our company when approving accounts, all of us have already seen the accounts multiple times. We have been there when the accounts were being made. The minutes of the meeting are more like a formal paper stating that we know what the accounts contain and approve their content, but it's not like we usually schedule an actual meeting just to waste each other's time.
Of course if there's say disagreement with the matter amongst attendees, it is essential to hold a proper meeting.
