That's exactly what happened, yes. There was a redesign in 2013, with new font for the logo and new lining. Some bags that were released at that time, such as yours, were somewhat of a mix between the old and the new styles.Thank you so much! What a pleasant surprise!!!
I was a bit concerned about the lack of PS engraving on the hardware and the names being close together on the inner tag. I imagine those details probably changed with time, as this bag has been in production for quite a while now.
