Are you sure you read that right?
I cannot think of a difference between a VA Appraisal and a Conventional one, other than;
Some Appraisers are VA qualified,
The VA requires that certain things be done, (primarily Health & Safety) if they show up on the Appraisal,
The VA sets the price for the Appraisal and some Appraisers do not like that.
It may have been a slip-of-the-finger; but where did you see this?
Good luck, God bless and have a good turkey day.
