The example was to illustrate that order matters.

YOUR casting skill has nothing to do with the lock casting skill for a reason.

Let's do it another way. What if I'm a SM with a sword that has 120% magery and 180% wield. My weapon has a ton of locks. I can put some blade spells onto it then activate the locks.

What if my blade spells expire first.. should my effective skill be the higher of my skill or the lock limit (220%). Technically I could rotate through swords and always have all the spells on right?

The only difference is I'd have to wait for the locks to expire, cast mine back on then reactivate the locks.
