You have to be trolling. The last sentence of the rule (and reading comprehension) shuts you down hard. "These must be at a different TARGET, which cannot be a unit forced to disembark as a result of the Split Firing UNIT'S initial SHOOTING ATTACK."
The only way that a unit can have a different target and an initial shooting attack, is if the unit initially had a shooting attack, which requires it to have a target. Note that is says "unit's initial shooting attack," and not "a model in the unit's special split fire attack." There is literally no evidence to support what you are saying. Absolutely none, you're reaching so hard. This is a very simple rule.
