I had never even heard of oxidative ozonolysis before, it's not even in my textbook so I googled it and it gives carboxylic acids instead of aldehydes.
Ozonolysis is an oxidative technique, it is the work up which is oxidative or reductive, but yes oxidative work up gives the acid rather than the aldehyde.
Good work looking it up, many people stop bothering once they have the answer they are after!
