Blucher recon rule query

[Last Hussar]

Have we read this right -

You can send as much cavalry as you like on recon, and it all arrives on battlefield, usually on élan minus 1?

What can't go?

Our reading means you get slightly weakened cav from first turn, no possibility of dicing from turn 4 onward.

Seems to make Recon very powerful for actual game deployment.
