Yes, this is what I had found too when I looked into this back in the Feb 2024 post made by @Peter_Hawkey
At the time it had looked to me like the expression map was configured correctly but was not behaving correctly, only in the case of the swing, and what it showed in the playback techniques lane in the piano roll was different from what it was actually triggering.
It is possible that the note length condition may not be working correctly for some reason when the note lengths are adjusted by the swing. I wonder if this might be related to the way that playing technique regions work when note offsets are used, regarding the timing for the keyswitches.
