Oswald is "infiltrating" a Walker meeting for the same reason he's photographing Walker's house: He's stalking the guy.
Frankly, I'm not convinced that politics played a very large role in the Walker shooting. Consider other assassins and would-be assassins such as Hinckley, Bremer, and Chapman. Each considered other well-known victims prior to settling on the person they ultimately shot.
Put simply: Walker was near the peak of his 15 minutes of fame and was accessible. Oswald may have disagreed with Walker, but how many of us would kill someone over a political disagreement? Oswald was a man who wanted to kill. His excitement over the planning and execution of it and his frustration over its failure point to that.
The main difference was that Oswald didn't have to stalk his second victim. His victim came to him.
