Naming 'n' instances or repetitions

I've noticed two ways of naming things 'done n times'.

In SwiftForth there is:

  (.0) (H.0)

which equate to executing '#' 'n' times.

It's not clear to me why '0' was used though '0' appears in forth naming
conventions meaning 'initialization'.

In VFX Forth (and perhaps others) there is:

  NDROP

where 'n' indicates number of executions.

In DX-Forth I have:

  NHOLD (H.N)

mainly because I couldn't think of anything else but willing to change
if there were a consensus.

Does anyone have knowledge on the matter or conventions etc.?
