I suspect that since they've also got an ILS to 01, as well as an NDB to 01 in addition to the LNAV or WAAS 01 procedure, there would just be no sensible reason to circle from a 19 WAAS procedure to get into 01.
edit: The only approach to 19 is the WAAS/LPV however, so if you're not WAAS equipped, the only other way into 19 is to circle.
Above my pay grade however and only offered as a comment on said Captain's aviation savvy. I wonder which missed approach he would chose to fly?
It is odd though and maybe it's the only example like that...
