CDO mergegrid applicable on a non-rectilinear grid?

I have 16 netcdf files (without a time dimension) on a global scale that contain the same amount of longitude grid points (namely 432) and the same amount of latitude grid points (namely 324). Each netcdf file contains a slice of data, for example in file 1 there is a data slice from latitude range 90 to 80 and in file 2 there is data available from latitude range 80 to 70. I want to merge these files which each contain a different slice of data to obtain a complete global dataset.

I have tried to merge the netcdf files with cdo mergegrid as described in this answer https://stackoverflow.com/a/51566286/20668027 and that worked as far as I could see, however, when looking in the cdo guidelines it was stated that cdo mergegrid is only supported for rectilinear grids. The grid that I am using is not rectilinear but since it seemed to work on my data I was wondering if I could still use cdo mergegrid? Does anyone have insights about this?

Thank you very much in advance!
