Well, the fire-and-movement tactics would resemble skirmisher tactics of the Roman times somewhat, but not the main-battle formation... though if you picked US Civil War as the era he would recognize that.
All in all you're correct... the underlying priciples are the same, the method of application changes. For example, the Romans certainly understood the principle of "fixing " the enemy by engaging him with one force while manuvering with another... but in their time they would have fixed the enemy by engaging him at arm's length with infantry while manuvering with cavalry.
Archery at the time was used more like field artillery is now... it provided attrition and confusion at range, but the best defense against it was to move out of the impact area, rather than taking cover. The idea of fixing the enemy with archery would have required a huge number of archers... a force which had that many archers compared to the enemy likely would outnumber them so signifigantly that there would be little question of the outcome anyway.

His weapon is different yes, but it can be referenced to a Bow or ballastia as it has range and striking power. give him a day or two to understand basic fire and movement tactics and he will see some simularity to his own fire and movement tactics with the Pilum and Gladius. The tactyics of there foew would resemble the bandits and zealots he fought in either Britian, Spain or Judea
