Many thanks to Peter and Darian for clearing up my misunderstanding of how vkResetCommandPool works. The manager creates command buffers from the command pool on an as-needed basis (when the queue of available buffers is empty), and keeps track of those buffers in a queue. When the pool is reset, the queues (one each for primary and secondary command buffers) are reset such that the tracked buffers are available again.
