The text will remain the same printable size, but you may find it moves about in relation to the site plan depending on the anchor points used.
I find that if you want to use the same plan at different scales, it is best to have two annotation layers.
One for each scale that you can control with layer combinations.
The layer combination is saved with each view of the plan so it is all automatic.
It just means you may have to annotate the same info in the different layers but in a position to suit each scale.
If you only have a few annotation elements you may get away with just the one layer.
But if you have many notes then I find a layer for each scale is best.
