Yes, it's correct, at ambient temperature of 120°C, whatever that means. At lower temperature more is permissible.
Also, the datasheet is wrong. It's not |Vo|-|Vs| but |Vo-Vs|, where Vs is the supply rail which supplies current to the output. So V+ for sourcing and V- for sinking. It can make a difference if supplies aren't symmetric or if you drive a load referenced to the opposite supply rail rather than ground.
Wait, no. It's not entirely correct. It's only correct if supply-output differential is at its maximum. If you drive positive current at 10V below positive supply, you only are concerned about current limit for |Vo-Vs|=10V. If you drive negative current at 10V below positive supply, then |Vo-Vs|=40V.
