Yes, but it's clear he obviously was keeping his defenses low for a reason (possibly war matchup, who knows).
Maxed lvl 11 walls are more than all defensive upgrades resource wise gold alone combined from TH8-10 more than a few times over, so again this was intentional... i.e. not normal progression. 2 walls is a maxed inferno tower lol, and you have 250 of them.
People who normally upgrade are max defensive way before walls and heroes are even remotely close to maxed (especially Th9/10) where walls and heroes cost a fortune compared to previous TH's.
This is evidenced by all the max defensive TH10's you see on a regular basis with weak walls/heroes. Just look at them. If it were so easy, they would have maxed them already...but alas that's what happens when you upgrade prematurely and don't optimize loot at your respective TH. Just prolongs the inevitable. That or they end up gemming them, lol.
