This is fallout from usr.bin/tic.c:

revision 1.33

As described in tech-userlevel:
- Modify the writing code to only write entries in the new
  format for the terminal descriptions that require it.
- Store new format entries as <name>@v3
- Store old format entries with clamped values as <name> for
  backwards compatibility
- Lookup first <name>@v3 and then <name> if that is not found.
- Don't create terminfo2 anymore; old programs keep working with
  clamped entries, and new programs be able to use the wide
  fields with using the original db file.
------------------------------

especially this part of process_entry:

        if (tic->rtype == TERMINFO_RTYPE)
                return process_entry(&sbuf, flags | TIC_COMPAT_V1);


but I don't understand how it is supposed to work.
