ELI5: When you try to load a page, and it loads right as you press refresh, what happens there?

This may seem like a dumb question, as it could be purely out of coincidence, but could it have something to do with it cancelling the loading process to reload or something.

It's not always coincidence!  

Sometimes when you see a part of the website flash just as you reload it's because the browser momentarily displays whatever it had already loaded, up until the point you hit refresh it was waiting for some data the website was supposed to provide but never did, so when you hit refresh this is aborted and the browser displays whatever it already has loaded, many times this is actually enough to make the website appear complete but maybe some functionality wasn't loaded yet.
