Yes, JL/JG/JLE/JGE are for signed comparisons while JB/JA/JBE/JAE are for unsigned comparisons.
Other architectures use LT/GT/LE/GE for signed and LTU/GTU/LEU/GEU for unsigned.
POWER is special in that it has separate "compare signed" and "compare unsigned" instructions, and the branches are just less than/equal/greater than.
