Can match loads be introduced on both of the interaction zone alliance tiles. It only mentions “the” starting tile.
If your question is referring to a standard VEX Gateway Match, you may only introduce Match Loads on Alliance Starting Tile in your own Interaction Zone.
If your question is referring to the Skills Challenges, you may introduce your Match Loads on either Interaction Zone Starting Tile. Please see the following past Q&A entry for more details.
Yes I was referring to the programming skills challenge. Sorry I didn’t mention it. 
Thank you.
You’re welcome.
