Re-deploy software to reimaged client

Morning all,

 I'm looking at PDQ to deploy all of our software but I just had a quick question, if I schedule an install to happen every hour but tick "stop deploying to computers once they succeed", am I right in thinking that once installed it won't keep reinstalling it every hour?

Also if I re-image a machine but call it the same name and put it in the same OU will the software ever be installed again? (Don't have PDQ inventory but can have SpiceWorks) or will I have to manually push the software to that machine?
