In case you haven't figured this out yet, \lblot is defined to be a
math symbol (\@mc is made equivalent to \mathchardef on the previous
line "\let\@mc=\mathchardef").  The family of that character (the
second hex digit) depends on the current value of \oxfam (see
definition of \@fz, which basically produces a hex digit corresponding
to the value of \oxfam).

See The TeXbook for explanation of \mathchardef and math symbol
definitions.

HTH,
Oleg
