Yep - have a look how they work:

Notice because it's sloped, the following pin would be jammed up against it (due to your foot being on the throttle and it stretching the governor spring) so unless you removed your foot from the throttle, there'd be too much spring tension against the following pin on the LDA with it down.
I've seen it happen in the reverse, i.e. you jam your foot on the accelerator, the follower pin jams against the LDA pin, too much spring tension even with the pressure applied to the diaphragm, the LDA pin won't drop down - let alone when the pin is trying to come back up!
