Yes, this works. But you get a different answer: (-1)^(-1/3) has the result 0.5-0.866025i and -1^(-1/3) has the result -1 as boggiani wrote.
It seems that the calculator interpretes -1^(-1/3) as -(1^(-1/3)).
If there are no brackets it should work from left to right.

Look at your list of priority of operations on page 26 of the User's Guide. ^ comes before unary minus. Only operations that are at the same level are evaluated left to right.

Algebraic precedence
The HP Prime calculator calculates according to the following order of precedence. Functions at the
same level of precedence are evaluated in order from left to right.
1. Expressions within parentheses. Nested parentheses are evaluated from inner to outer.
2. !, √, reciprocal, square
3. nth root
4. Power, 10n
5. Negation, multiplication, division, and modulo
6. Addition and subtraction
7. Relational operators (<, >, ≤, ≥, ==, ≠, =)
8. AND and NOT
9. OR and XOR
10. Left argument of | (where)
11. Assign to variable (:=)
