Looks like you can opt-out of the relay service. From the very bottom of the article:
Traffic Relay ... You can opt out of this, but it could result in peers not being able to network with each other.
BitTorrent Sync allows for LAN syncing, yes. When a direct connection between hosts is not possible, it will use a third-party server as first a matchmaking server for NAT hole punching. If that fails, it will route all sync traffic through the third party server acting as a relay. (These third parties are controlled by the BitTorrent Sync developers)
You may need to have some way of killing the btsync daemon on your home machine if you want to sync directly from your laptop to your office machine.
