The simple answer is that if a sub-prefix can be specified that is
unique to that DXCC entity (i.e. PY0F, PY0S, PY0T or VK9W, VK9L,
VK9C), then that prefix (without the slash) is used as the "reference"
prefix.  HK0M is not a unique prefix for Malpelo; in fact, other than
HK0TU, and an HK5/0 that was on a few years ago, I don't know that any
other callsign has been used from there.  HK0 is/was also used from
San Andres, Bajo Nuevo and Seranna Bank.  So that is why the /
notation is used.  Same for VP8s, E5, FO, etc.
