Debuff spell on Summonable Death Unit

[Inferno]

Hi All,

On my last game I has situation, where I have cast Debuff spell  "Fading Vigour" on Summonable Death Unit {Bladegheist Revenants}.
Then unit was destoyed. My openent brought this unit back with Enless Legion ability.
I wonder if unit still has "Fading Vigour" Debuff as it should last till my next Hero phase, and basing on Comand Ability wording player is allowed to bring back destoyed unit. (exactly same unit) "You may pick a friendly summonable unit that has been destoyed..."

Core Rules FAQ contains following answer, personally I think that in case the unit remains the same, debuff would still be applied.

Q: If a unit leaves the battlefield for whatever reason and comes 
back, do they lose any bonuses they had from abilities or spells? 
Also, if they had a ‘once per game’ ability, does it reset?
A: If a unit leaves the battlefield and then returns to 
the battlefield, no to both questions. If the models have 
been slain and are being used as part of a unit that has 
been added to the army, then yes to both questions.

Personally I think the answer is no Fading Vigour does not carry over, as the unit is treated as a brand new unit for rules purposes (not counting towards kill points in matched play for example), though I could be wrong

I am not trying to push this idea through, though in my opinion you are wrong  this isn't brand new unit as basing on the Battletome you summon killed unit, hence same one.
