Yes. This is specifically a driver for having brand-specific sizing: knowing what size I am in Wooland Jade does nothing whatsoever to help me assess a potentially cheaper option in Uniqlo Whatever. It's the same lock-in effect as cloud APIs, only implemented through attributes instead. Imagine the chaos in the guitar market if the "bass" in "bass guitar" had up to +/-25% variation between guitar manufacturers — it would be a total nightmare trying to cross-shop guitars away from your current one, and lots of people would just end up glued to a brand so they don't have to do the hard work of assessing 'is this within +/-5% of the bass that fits me now'.
