The "special" byline is often used when you choose the same thing multiple times.
I believe in this case, you can accumulate multiple copies of this boon but you can only cash them one in at a time and once per adventure. When you do so, the boon is expended.
For example, you could purchase 3 copies of this boon and spend all 24 days of downtime after a module to have 3 Practiced Medic Boons on the same PC. In the next game you play you spend one of them to make a check better. Now you have a total of 2 copies on that PC, and you can't spend either of those copies during that same adventure.
Thank you for the clarification Doug. I appreciate it.
