Your reputation is only as good as the people who know it. Most HR will not have heard of you (unless you are a high-profile leader in your field) and hence the desire for a rubber stamp from a brand company. It's the same reason many people desire Ivy League education, not for the learning, but the brand name that will make entry to most jobs a lot easier (as HR/Company assume certain level of quality/competency/work-ethic/etc has been met).
