Hello Alan (Al985 )
Salvage radiotherapy after failed surgery is usually 33 fractions as normal for this type of case. From talking to my radiologist (I am a bit of a nerd when it comes to PCa) it's done for clinical reasons. It's done to catch cancer cells the surgeon missed and as these are smaller doses than the 20 fractions it gives better protection to your rectum and bladder - don't forget you don't have a Prostate to protect these bits of your anatomy.
You will be fine - you've already had "the bad apple in the box".
Well don for contacting "Maggie's".
To keep your mind occupied on other matters apart from your surgeon, here's a link to some reading material:
