Hello,
Your understanding is correct. The documentation for these two operators is:
BetweenInclusive
returns true if the first value is within the range defined by the second and third values (including the bounding values).
For example, X BetweenInclusive(50, 100) returns true if X is greater than or equal to 50 and less than or equal to 100.
OutsideExclusive
returns true if the first value is outside the range defined by the second and third values (excluding the bounding values).
For example, X OutsideExclusive(50, 100) returns true if X is less than 50 or greater than 100.
Note: The OutsideExclusive operator has the same effect as Not (BetweenInclusive).
Let us know if you have further questions.
Thanks,
Sam
