You could say that, yes. But there is no denial that there is an evolvement with most of the lines designed under the Yohji Yamamoto umbrella to look a whole lot more 'streetwear' if you want, focussing on 'staples' that have been repeated so many times (beginning with the rightfully closed 'Coming Soon' line that was all but a disaster). It's alright if there is an outlet for that and I understand not every Yohji customer wants the 'grand gesture' of the mainline, but there is no need to do what seems like an endless riff on the same sarouel trousers, knits and basic wool gabardine blazers in all of the Yohji collections. You ultimately want to address different needs with each of those lines and not have them compete with one another.
I am also pointing out that specific time frame in the early to mid 2000s because I firmly believe that Y's having a runway show in Paris made the team deliver more specific, often times also more intricately detailed pieces - Epitomized maybe by the insanely craft-y AW'2003 collection with it's Shibori-dyed, hand-frayed and later on hand-crocheted gabardine pieces.
