Pretty much. The limiting step is waiting for the sprayed weeds to die. 
The weedkiller loses its activity on hitting the ground (as do one or 
two others as they adsorb strongly onto clay and are then more slowly 
chemically degraded).

Ivy seedlings and a few other extremely waxy plants can survive some 
glyphosate spray, but it isn't something to rely on. And grass is 
exquisitiely sensitive to it so be careful not ot walk across a lawn 
after using the stuff if you got any on your boots.
