..in that example, the bud union is just above the ground.. all suckers there are from the rootstock, both below and above ground.. above ground suckers from rootstock occur just below the graft, as the graft was not buried, and where a node that remained on the rootstock was not removed by the budder at the time of budding..
Roots and rootstock aren't the same thing @Hostafan1 Roots are under the ground and the root stock is developed as a disease resistant stem or trunk to receive the desired plant and protect that plant or tree from disease such as phylloxera. i.e. fruit trees, grapevines etc.

Roots, and rootstock can be different, as in 'own root' roses, some of which can sucker from their own roots, just that it'll be the same plant popping up..
You're , or course, 100% correct, but as the overwhelming majority of roses sold, are not " own root " roses, effecitvely the roots and rootstock ARE the same in MOST cases, including that of OP.
