If the choice is to get the training in the way you are doing it or skimp on training, then you are doing the right thing. I wouldn't worry about what I'm not getting. Focus on what you are getting. Your body will give you the feedback to know that you are making progress. For what it is worth, I split my workouts all the time. Sometimes doing the squat and deadlift in the morning and press and chinups later in the day, and sometimes splitting the to two different days. Time in the gym is hard to find sometimes. Get it where you can.
