Shortcodes and Tiered Membership

I had a question regarded Tiered memberships and the usage of shortcodes within the plugin. I have three memberships levels setup we will call them A B C with A being the lowest tier and C being the highest tier.

I was under the impression that with tiers I could set it so that content available to A would also be available to higher tiered memberships like B and C. However this isn't how it seems to be working when I use shortcodes, am I mistaken in how the tiered products work?

I've found a workaround using if statements to output the content multiple times with each shortcode depending upon what category the post is, however if there is a cleaner way to do this I would prefer that.

Thanks!
