No, I have measured the pin, the clock is only out when IEP1 is also configured. So in sysconfig, the PRU IEP section, V12 appears to be mapped to IEP1. When IEP0 is selected, V12 turns to grey and is not selectable. From your argument I believe V12 can also be mapped to IEP0. But there is just no clock. Yesterdays project I have to first run IEP1 code, then IEP0 code, and get SD_Clock.
