Well, they just said it looks like basic filters, and to an extent they are not wrong. PS has had filters that give a "paint" look/feel to it, and they would still be useful to do this in PS. They didn't say that's all that would be needed. Those filters are basic filters in PS as they are included and not 3rd party separate purchases.
Your interpretation of the original comment into saying it was simple is a bit skewed
