Depending on the tool in use, dynamically rotating the drawing plane axes yields slightly different results. For example, consider the scenario of placing a block (rectangle) with the Place Block (Orthogonal) tool, which takes its orientation from the drawing plane XY axes.

Once the drawing plane axes are rotated, the block's main axis is constrained to the rotated XY axis.

Contrast this to the effect when using the Place Line tool: The drawing plane axes rotate, and while dynamic readout is a function of the newly rotated system, the tool itself remains available to dynamically place the line wherever desired.
