welcome! with all the bradford pear around, i’m surprised you’re not growing any pears for yourself…they make a pretty solid rootstock for all kinds of edible varieties if you get into grafting.
girdling trees keeps them from storing more energy in their roots, but it can still take a while for them to use up the energy they already have stored. i’m sure the time it takes varies by species somewhat. i girdled a big tulip poplar at my place and it took 4 years for it to die.
i see this in sunflower family stuff a fair amount - sunroots and yacon. it doesn’t seem heritable, from what i’ve seen. those shoots that have it seem to have a slight advantage to their neighbors in growth - could well be from having half again as many leaves?
