Is it necessary to place different membership level forms on different pages?

I have placed five membership level forms on the same post or page in WordPress and I receive the following warning:
“Detected more than one s2Member Pro-Form. Please use only ONE s2Member Pro-Form Shortcode on each Post/ Page. Attempting to serve more than one Pro-Form on each Post/ Page (even w/ DHTML) may result in unexpected/broken functionality.”
Is it necessary to place each form on separate posts or pages?
Thank you…

Having different pages for each option is easier to browse perhaps but you can always put more than one option into a page like this
