yes you can. If you do that on the last entry, I believe a person can stay for 9 months on the Multiple Entry Tourist Visa (if my math is correct).
If a person enters on the last day the visa is valid, they will be stamped in for 59 days.
They can get one 30 day extension of stay based on tourism added on.
The total length of time is 89 days.
