Triggless p-lock doesnt play on same step when externally sequencing

When I use an external sequencer to sequence my model cycles, if I set a trigless p lock on the same step on the cycles it doesnt have any effect. If I set it on a step after where the note is played it seems to work though.

Is it not possible to get the p lock to apply on the same step as the note when youre using an external sequencer?
