How to connect ST-LINK/V2 ISOL

I'm trying to connect new ISOL version debugger to a device I have been debugging with the old ST-LINK. I do not have 20-pin JTAG on my device (small battery operated STM32L100) and I try to get only 3V3, GND, SWDIO and SWCLK connected. My problem is that the ten pin cable provided with the debugger fits to ST-LINK only one way and the User manual UM1075has a table 4.2 Connection with STM32 applications which suggests the pins would be 1, 20, 7 and 9 in the same order. Then again Figure 10. JTAG debugging flat ribbon layout shows that I should but the connector on the row where it doesn't fit because of the polarity pin. Which information do I trust now (and why would the 10 pin connector be fitted on the row that has only VCC and GND on it?) Anyone have a picture of the actual ST-LINK with the 4 wires connected?
