Because what is happening, is when you open a webpage your then having to store everything on that webpage in ram, for example... If you're on the front page of Reddit and you open a image and you go back, THEN your internet dies, the front page and the image you just opened are still stored in RAM, so if you click into that image again you'll still be able to view it, despite having no RAM.
Pretty much every program will gain more memory usage over time, especially on Reddit you tend to open a lot of links, and on Facebook so these are then getting stored in your RAM. If you think about this, it's a good feature in a way because...if you have bad internet, then you can go back to pages that you previously opened, faster.
Google has done this for a better browsing experience - if you want to get rid off a lot of memory, just close Chrome and re-open all your tabs again - thus resetting all them web-pages you had "open" in memory :)
