Latest update of the Clarifications is up on the MeG website - https://mortem-et-gloriam.co.uk/meg/ - under the Rules drop down menu.
OK, thanks to Ray's eagle eye spotting that one of the clarries was not consistent with the rules we will be putting out an updated version in a few days time.
However, in order to keep you all informed here is the updated wording of the clarification in question as it will be in the revision:
• IF YOU HAVE THE DISMOUNTABLE CHARACTERISTIC, CAN YOU DISMOUNT AND MOVE IN THE SAME PHASE? No you cannot. Dismounting is a Prompted Action (see Glossary definition on page 218) and is not one of the exceptions to being restricted to a single prompted action or charge per turn listed under Universal Rule #14 on page 80.
