It definitely used to behave like that. But on the latest firmware the physical button now immediately moves the toolhead into a “pause” position above the poop chute and then pops up a dialogue asking if the print should continue. Better behavior than before, but not to be treated like a “kill switch”. Have to flip the power supply switch in the rear to immediately halt all movement.
FWIW I appreciate the current implementation but agree the symbol on the button is confusing.
