Name: Big Bill Livonia Michigan (Zone 6a) If you need to relax, grow plants!!
He was probably under the notion that he was installing a privacy barrier. Cutting back the top leader will stunt their vertical growth some what.
Personally I would leave them alone. You can only cause them more stress by moving them again. That will be twice within a calendar year.
I think that they will be fine. Just make sure that they get adequate water the rest of this year to help them establish. Make sure that they go into winter well hydrated so they will be less likely to suffer wind burn.
