Interesting you should ask this. I asked this same question of Herb Belin at S&W (he was at the time in charge of revolver production and the X Frame was his baby). He said it was not necessary and did not expound any further. When I pressed him on the issue, he simply said that tests had proved it was not necessary.
Now, if I recall correctly, the reason for the lengthened bolt stop notches on the N Frame was that high speed photography had picked up on the cylinder moving far enough that the cylinder stop would come out of the notch, and the longer cut simply insured that when the cylinder moved the cylinder stop stayed locked into the notch.
Why this was not necessary on the X Frame is a mystery that Herb did not really clear up for me, other than to assure me that it had been tested and was not necessary.
Thus, in the end, your guess is as good as mine, although I was assured they had "thought of the problem."
I wish one of our resident engineers or someone else with "inside knowledge" would take a stab at this one.
By the way, I have not read any reports of the X Frames in either .500 or .460 having incidents of the cylinder stop jumping the stop notch. Have you read or heard of this?
