It does not trail when you change from 1 channel to the other. it only trails when you bypass the current channel you are using.
channel 1 : bypassed = trails
Channel 2 : to Channel 1 = no trails
When i play the crystal effect to immitate a synth, my next riff is a lead part with delays on the other channel. I switch from crystal to my chorusy delay setting and the crystal effect cuts out immedietly resulting in an unnatural interruption of sound.
