It is common that if a tool cuts a long time especially hogging, it may get stuck in the spindle. The tool release cylinder typically releases the tool but also has a knock out at the end of its stroke of about .030 inches. It may be that the cylinder releases the tool, the drawbar starts to press on the retention knob, pressure builds, and it pops.
But the fingers should still be around the tool and beneath the spindle.
Maybe the tool unclamp switch on top of the drawbar is being seen too soon and the tool fingers are already retracting when the tool pops out.
Watch carefully.
