Ya, although we still only have limited information. That Doctor (and Coulson) only seem to remember the (supposed) 7th surgery, although Coulson did seem to have some flashbacks related to a bodybag being zipped up and some glowing blue stuff (Super Serum? HYDRA tech? Cosmic Cube?). I honestly think it's a slight bit of misdirection and there is more than meets the eye. Nick Fury expending a ton of resources to get Coulson back suggests that there is some manner of tech or something else that makes him a priority resource for SHIELD. Agents die all the time and Fury doesn't strike me as being overly sentimental. However, if some game changing piece of tech or project was lost, it would make sense they would want to get it back no matter what...especially if that thing had global consequences.
