They should be alright, but may have a bit more winter damage than you would like. Why? Because I expect those vines to push new leaves this fall, which will be a net loss of reserves in the roots. With any luck, the new growth will get large enough to replace spent reserves before a freeze this fall. When we talk about pruning in the fall, it is after dormancy sets in. Good luck/ Oh and you better set up some really big rat traps. LOL
