He may or may not be, article doesn't say. Anyone who enlists or is accessed as an Officer has an eight year obligation, active or reserve in any mix. If he enlisted back in DS/DS days, say in 90, his obligation expired in 98.

Involuntary recall for 'vets' as the article states thus are good only for that eight year period. Rarely, there may be case where there was some obligated service due to special training or a promotion that was waived so the person could be released from active duty and then they could be called back to fulfill the obligation -- but that is really unusual.

Active or Reserve retirees OTOH are obligated from date of retirement to age 65.

Probably a screwup...
