Not everything that someone does is for a reason. There is a person on Twitter who calls themselves a Master Persuader but can't seem to convince anyone but the group of sheep that follows him. One of the things he likes to do is take what someone says and then reverse engineer that into some brilliant persuasion strategy.
Most of the time people are slinging shit and seeing what sticks. There isn't a grand strategy behind everything. These days especially if you spend time on Twitter everyone thinks everything is multi-dimensional chess.
After the fact it is simple to take something and try to turn it into a strategy. The harder thing is thinking of it before and actually having a strategy.
Bottom line, just because someone tells you a strategy is brilliant you aren't required to believe it.
