2 year Army HPSP

Hi all. I’ve been thinking about applying for the 2 year HPSP and I was wondering if the same opportunities exist for a 2 year recipient to specialize as a 3 and 4 year. Also what would the payback period look like? For example if I did a 1 year AEGD and then a 2 year Endo residency then I would owe 3 years after right?
