Yes, there is a little problem. If you have table open in shared mode and then try to open it again exclusive it would not give you any errors, but would remain opened in shared mode. So, you should always do

use in select('MyTable')
try
    use MyTable in 0 alias MyTable exclusive
catch to loErr
endtry
