There is a lot going on here.

My first thought was to see what happens if I set all three of the variables to 0, and then all three of the variables to 1. Each of these conditions satisfies both statements.

Give that a shot and see what you think. In general, when there is a lot going on in an inequality question, plugging in can be helpful, especially plugging in boundary values.
