   Would like to enquire, for multiple update actions, how would overlapping matched actions be evaluated? 
   
   For example:
   ```sql
   when matched and target.age = -1 then update set name = source.name, age = source.age
   when matched and target.age > -10 then update set name = source.name
   ```
   
   I am not really sure how traditional SQL parsers/engines handle these situations.
