[Rules] 4th Edition Recce and Spotting rule 8.23

[Hugmenot]

Interpretation 2 is correct in my opinion.

They recce unit must be able to spot the enemy unit. The "just as if the enemy unit had blown its cover by firing" was to reinforce
the concept of putting Spotted markets on units in limiting terrain after they fire (provided they are within LoS and normal distance, typically 12 hexes, of an enemy unit) .

Just a case of an attempt at a clarification ending up causing some confusion. Writing precise and complete rules is a very difficult task.
