I think I now know what's happening (at least mostly).

perl5db.pl uses the magic typeglob PL_DBline (aka DB::dbline) to
set breakpoints.

The magic for this typeglob calls Perl_magic_setdbline, which
sets op_private of the COP associated with the breakpoint to 1 or 0
as appropriate.

Im not sure where the value 2 comes into play, though.
