"Absolutely what happened."
Then you were doing something wrong.
When properly booted from ANY drive (external, internal, or a combination), when software update is run, it runs "oriented to" the volume it's booted from, and NOT relative to WHERE that drive is located.
That's been my experience over 31 years of Mac computing.
I've never seen or experienced things to behave differently.
