"B. All Army personnel in uniform are required to salute when they meet and recognize persons entitled to the salute. Salutes will be exchanged between officers (commissioned and warrant) and enlisted personnel, and with personnel of the Armed Forces of the United States..."
The regulation is the regulation... A salute needs to be rendered. But not because the regulation says you have to, but for respect for the rank. The 1LT (probably a PL or staff guy) is starting to lead in the wrong direction and if/when his feet start getting held to the fire for problems either in the platoon or shop it's going to be harder for him to gain a command type authority from the rest of the guys to fix it. At the same time he's letting the 2LT slip by with it and starts setting him up for failure if not a rocky start when he's placed in those same shoes. I'm not saying they don't work well together but it's a visible sign that puts off false expectations to everybody else.
But I bet he gets upset when he gets promoted and the new 2LT gives him the same speech about saluting.
