I see what you mean, but the order of the objectives is not important when it comes to the exam structure itself, which after all is the primary purpose of the blueprint - questions on the blueprint objectives can be asked in any order during the exam.
The blueprint has to start and end somewhere in terms of the order of the objectives, to add to your point above you'd also have to setup ESXi networking and datastores before deploying VCA, yet in the blueprint networking and storage are later sections of the blueprint.
