I also agree with the sibling post on this one, but another line of reasoning is that when texting pictures or other forms of sending, the default option is that the photo is saved. When using snapchat it's the opposite. Screenshotting allows you to keep it if you want, you can replay it if you missed it, but if it's not anything exceedingly special or worth keeping, it is discarded. In todays world I find myself with far more data that I can keep organized, and a lot of it is not of any particular value. Another way of phrasing that argument is that if you look through my snapchat screenshot folder vs the received images from my SO, the snapchat screenshot has a higher density of content worth keeping.
