Not true. If you call Kelly Rockwood, PADI training and QA, she will tell you that the self reliant diver course is meant for a recreational diver to plan and execute a buddyless dive. It is called Self Reliant because Karl Shreeves or Drew Richardson, can't remember who, wrote a missive stating unequivocally that PADI would never endorse solo diving.
You are, however, correct if you apply the self reliant diver course to IANTD. I spoke to Eric Keibler, who was or is on the IANTD Board of Directors, and he told me that the IANTD self reliant diver was to train a recreational diver to safely complete a dive in the event they found themselves without a buddy.
