Why did I need to restart to upgrade my recovery partition?

I tried to upgrade my recovery partition today and it failed with "No such device"/OS error 19.

I found this discussion on Reddit in which @mmstick suggested restarting, but with no explanation as to why that was needed or would work. It worked for me.

I'd like to know why it worked and why it was needed, mostly for two reasons: to generally understand the situation better and to imagine what I might have been able to do that didn't require restarting.

Thanks.

Standard IT practice to turn it off and on again. Some updates require system restarts to apply the update to the running system, otherwise you may see some broken behavior where something's inaccessible because the installed drivers don't match the kernel you're using.

- I am familiar with this. It also doesn't help me understand much more than "it's complicated". I already suspected as much. 😉

  Emphasis on "running system". Similar to how you can't fully re-partition a disk you're currently using.
