Script copy paste layer color profile mismatch

Actually, this code works and bypasses the Paste Profile Mismatch alert dialog without having to disable the alert box manually.

In this case, does Photoshop silently convert the paste information to the destination document color profile? 

I don't always know if the alert box has been disabled. I am trying to bypass the alert box in case it has not been disabled. Is there a way to check if the alert box Paste Profile Mismatch has been disabled?

That would be the case if the color mismatch alert dialog is off. What happens if the PS system color profile alert dialog is on and the user runs the script on a batch of 100 images. Will the alert dialog pop for every single image with a different colors profile or only the first time it encounters the mismatch and the user checks do not show this message again? 

I was afraid the double copying would damage the file by causing data loss when going from Adobe RGB 1998 to sRGB and back to Adobe RGB 1998. In the workflow, the script opens and closes the source doc before opening the destination doc. So how would the comparing docs work? Do both source and destination doc need to be open simultaneously?
