Do higher limit players normally play horribly when playing down?

[redfisher]

Do you think that high limit players have a tendency to play badly when sitting in a 1/2 game waiting for their 2/5, 5/10, or 10/25 seat? I've noticed a tendency for them to essentially bet all streets at the standard level for whatever game they're waiting on. Is this common? Is it just one of the many joys of playing in the Deep South?
