Yeah I usually keep one old save (several levels back, in case I've made some bad choices) and then have two current ones I switch between for conversations and also exploring dungeons etc.
I've kept that habit from TES III and used it all the way through TES and Fallout games up to Fallout 4.
Some people have more saves than that, eg like for Fallout 3 where you have different cheevos/trophies associated with karma at certain levels.
