Ok I can confirm that in this situation tracking doesn't start. I never experienced this because I almost always make a slew before the tracking.
In my logfile I parked and unparked the mount and then tracking works.
I don't know much about the eqmod-protocoll but I think that the mount says

[COMM] read_eqmod: \"=101\", 5 bytes read
when the tracking doesn't start
