You might be confused about the function of the various components of the Harmony system and/or how they communicate.
Communicates with the cloud via WIFI in order to get settings you have changed via the web.
Communicates to your devices via Bluetooth (game consoles)
Communicates to your devices via infrared via plug-in blasters and itself (in addition to the plug-in blasters, there are also blasters built into the Hub).
Communicates with your remote for syncing data via (not sure... RF?)
Communicates to the hub using RF. The hub receives the RF communication and then communicates to your devices as outlined above....sort of like someone who can translate from one language to another at the UN.
The hub receives RF commands, but it always sends commands to devices as IR or Bluetooth.
Can communicate directly to your device via infrared, but ONLY if you have activated it at my harmony.com or in the remote settings (default is hub+blasters). Assigning IR to the remote for a device then stops
the Hub (and plug-in blasters) from sending the IR to that device.
So in short, YES someone can get in the way of IR being sent from a blaster or the remote (if it is set to transmit IR) but just wanted to clarify what is being sent, and from where. In its default mode, the remote does not actually communicate directly with your devices...the Hub does.
If anything above is incorrect I'm sure someone will advise and I'll edit.
