Yes toe is what scrubs a tire and causes the MOST amount of improper tire wear, but negative camber can have the same effect just not as fast. Moving the contact patch that much (up to -4*) will DEFINITELY cause improper wear. You are riding on the inside half of the tire, its inevitable over time to half uneven wear.
What I do for these types of applications is have the tires dismounted and remounted side to side around half of the tread life. This gets me the optimal use out of the tires since Im not just wearing away the inside edge until they are useless.
