Down dash and normal dash count as two separate dashes

[zacoxaco]

You can go over the one dash limit by using a down dash (holding crouch and dash) and then dashing normally. Or the other way around.

This is also possible with superior stamina to get 4 dashes in a row.

Dash -> down dash -> dash -> down dash

Down dash actually seems to have an infinite usage amount.
