these are two separate things entirely. One is the 90 day visa from Savannakhet or Vientiane, when you enter you'll get 90 days.
If you left the country before 90 days to go get the year-long, multi-entry visa your stamp would cancel when you stamp out.
Then you'd get the new visa from Penang. They have nothing to do with one another.
You're talking about getting two separate visas from two different thai consulates..
If you can meet the financial requirements in Penang for the year-long, multi-entry Non-O visa don't even waste the time going to Savannakhet or Vientiane for the 90 day single entry one.
