FYI, my response was based on a very similar situation. The OP wanted to splice a welder off the same circuit. I flat out told him and cited the fact that if both devices were on there would be an over-current trip.
I even took it a step further and used a situation where the dryer was installed in a location where the person using the dryer would not know that someone was using the welder.
Regardless, the NEC it said was allowable in the code.
It is not something I would ever advocate or do myself. But it is allowed.
Please remember that this is a DIY site geared to residential installations, so more than likely the OP has no real idea what they are asking about.
Also, I see no reason why you should not continue your discourses with Stan. We all learn when things get kicked around.
