It is neither a great nor original revelation that this kind of thing gets many people using XU stumped.

This is an issue with trading in general of course, not unique to this system: is it a retracement or a reversal?

Apart from the usual blah blah about higher timeframes and D1 open lines which can be similarly ambiguous, is there any reason (within the XU framework) to "ignore" the Green SEMA 3 (Star) and blue candle colour in the first image and go short off the red Big Dot?

Normally I would just move on and say "oh, well, that was not the setup", and wait for the next, but it does seem like an awful lot of good points going begging.
