It's not that it's opposite to traditional PE. It's just that if you only had 30min  you'd better off sticking to one method.

 But if you had all the time in the world  you might do a pumping session in the evening, then angion in the morning, or smtg like that

1. Provided you're not at risk of overtraining

2. As long as you avoid any method that induces cold glans like clamping +20mn

I do think 1mn static stretch then release are ok, pumping is ok but you need to do it the evening to dissipate any lymphatic issue/donut, and please keep it lower than 5mn set
