Yes, the gas station example is directly cited in the article I linked to. It’s legal for a gas station owner, with knowledge and consideration of a competitor’s price, to reduce their price to the same or just below. What is illegal is for nominally-competing gas station owners in an area to conspire to keep their prices within a range of each other’s, even without explicit agreement.

The article you linked seems to indicate that there has to be active communication between the gas station owners for there to be collusion.

When I worked at a gas station as a teenager there was definitely an unspoken implicit agreement that the price of gas would be 6 cents/liter above wholesale IIRC. Which was highly competitive and didn't completely cover costs.
