Yes it does, and that's why your second response is incorrect.Decarbing removes the carboxyl group -cooh from thca as co2 converting it(thca) to thc
When you decarb it changes its structure from crystalline to amorphous. So decarbing is a one way street and after its done it will not be a solid at room temperature ever again.Decarbed stuff will still make shatter just fine though..eventually.. depending on how much poop is in it, but you can turn pipe resin or reclaim into a cookie or shatter through the same drying, losing lighter constituents
