He might not be aware it's his job to plan the outing.
Could be any of those, or (in keeping with number 3), he may be expecting you to contact him on the day, if you're serious about going. If he doesn't hear from you, he may assume something came up, or you weren't really interested to begin with. Meet him halfway. On the day you agreed on, call him up and say "Hey, are we still gonna __________ today?" You might try adding "
I didn't hear from you, so I wasn't sure you still wanted to" but if he's an Aspie, he may not pick up on the hint the first hundred times.
