I think that is the advantage of having the support on both sides, unlike (my WWMM cart which just has support on one side. If you want to take a sheet out of the middle, you can lean sheets on ones side away (to the left), tilt the one you want straight up and slide it out without much resistance from either side -- probably just where they still touch at the bottom. With the wheels on the bottom, it should slide out pretty easily. My only concern with this design over the WWMM style cart is that it may not be that handy for storing partial sheets. The WWMM cart is rather short so full sheets stick out on both ends but it is really good for storing partial sheets of any size. I usually only have one or two at most full sheets at any given time but always have some partial sheets to store.
Here is the WWMM cart:
