I think this is referring to the fact that the standard temperature changes with altitude.
At sea level ISA+35 = 15+35 = 50C. At 1000' MSL ISA+35 is 48C. At 2000' its 46C. At FL200 its -5C, etc.
The ERJ has a similar limitation. ISA+35 is the max temperature for the aircraft. But max temperature for takeoff is 52C. How is that possible? Its because we can take off at -1000MSL, where ISA+35 is 52C.
