What’s the point of connecting to another machine with SSH to crack a password?

If anyone has heard of Ippsec and watched his videos, you’ll see that when he extracts a password hash from a machine, he doesn’t crack it in his own computer, rather, he uses SSH to connect to his other machine called Kracken, and then cracks the password with hashcat or john. Are there any benefits to this? Why would he crack it there instead of using his own machine?
