If it's long-term storage it wouldn't make any difference, because you should drain all the fuel from the tank and run the engine until the settling bowl and carb are dry of fuel.
That should always be done if you're not going to use the saw for several months or more.
Otherwise, between jobs I'd leave the chainsaw flat on its bottom. Many chainsaws have a tendency to leak fuel if not stored like that. It's also possible for raw fuel to run into the cylinder if stored otherwise.
