I do not have a 1992 copy, but my 1990 copy of D1.1 states that the progression for all passes of vertical welding shall be upwards except that undercut may be repaired vertically downwards.... In tubular structures the progression of vertical welding may be upwards or downwards, but only in the direction(s) qualified. This is listed for the SMAW, FCAW, & GMAW processes.
If the procedure you have was written as prequalified, I do not think it should have ever been considered prequalified.
Im thinking you are correct, ...that it is no good anymore.
