Yeah, I assume they refrained from saying the name because they could have been a overheard by an enemy soldier. Sort of like a code word. That was if anyone heard them talking about the Coordinate the other person wouldn't know what they meant.

Though, if they wanted to be sneaky about it, they should have had code words for their Titans so Marco wouldn't know they were potentially talking about transforming into Titans to kick holes in Walls. >.<
