Does marinating meat in a vacuum really open the pores and cut the time?

i was wondering becuase i normally marinate meats over night and they say on tv that in a vacuum its opens the pores and you can marinate in 30 minutes. can anyone confirm this?|||Not so sure it opens the pores but it pressure forces the marinate into the meat. I do it all the time with my seal a meal and a marinating canister. I can do 1.5 inch thick steaks in about 15 minutes.
