Given that the end result is in fact a single contiguous subtitle file,
the input must have been the same thing. I declare this is the face of
any and all evidence, and attempts to convince me otherwise will be
utterly futile.

At least this week.

As far as I know, the programs which mux subtitles into containers which
are intended to support them (Matroska, Ogg, NUT) do not themselves
combine multiple subtitle files for the purpose; it would not make sense
to me for them to do more than take one input file per intended subtitle
stream and mux that in. If a person has multiple subtitle files which
they want to be part of the same embedded subtitle stream, the task of
combining them is properly the job of a separate program.

The tasks you list above for mkvmerge are, as best I understand them
from the brief names, properly the job of a muxer. Combining multiple
subtitle files is not, if for no other reason than that it would very
likely restrict possible subtitle formats to those which the muxer
understands. (...which is where we entered this part of the discussion,
isn't it?)
