AddonRepository._repopulateCacheInternal(), and possibly several other internal and external AddonRepository APIs, perform callback-based async steps (e.g. AddonManager.getAddonsByIDs()) before issuing the actual XHR request and setting the AddonRepository._searching flag. If an AddonRepository.cancelSearch() call comes in during the async steps before the XHR starts, it has no effect and the search will still be performed.
