I mean, if a person's semblance is tied to their personality, a drastic change in one's belief may cause a drastic change in one's semblance as well.

Volume 3 probably shook Ruby's ideal viewpoint in life so her semblance evolved to reflect that.

So in this analogy, the swordsman is now using a catapult to launch swords.

This is just a speculation but there's likely a few rare semblances out there that can change overtime akin to the Glyphs becoming more powerful with training. Maybe a SEW trait.
