Audible Instruments Tidal Modulator: Potential bug?

Is it just me, or do the high and low tides outputs on the Audible Instruments Tidal Modulator plugin not function correctly? AFAIK, high tide should produce a signal at the end of the attack phase, low tide should produce one at the end of the decay phase, and both will hold until the envelope cycles again… It seems that high tide is just outputting a signal during the entire attack phase, and low tide always produces a signal no matter what. Is there something I’m missing?

It’s not something, I’d ever bothered with (I use Tidal as a VCO mostly) but I can confirm this observation.
