Grid snap should work for placing those type of points on to a grid.

But if you are dragging objects around after you have drawn them, it is certainly possible to get an end point off the grid if you end up placing some other point of the object on to the grid instead.

For example if you grab a line by its midpoint and drag it around, you will then be actually placing the midpoint of the line onto the grid and that may mean that the endpoints aren't on the grid. So if you're dragging objects around and want them to end up on the grid you probably want to drag them by their endpoints, or possibly use the Transform > Move command to reposition pieces instead of dragging, since you can then put a base point for the Move to be somewhere on the grid and not necessarily actually on the object like will happen with dragging.
