B737 Igniters

Hello Ladies and Gents.

I always thought until now that in the case of a loss of both engines, after applying the memo items and setting the Start Switches to Flight you would get dual Igniter sparking in the engines while trying to recover the situation.
Though, as the L - Igniters are powered by the respective AC transfer Bus these will not be powered as there will not be any AC available from the engines (unless of course APU is available). Only the R - Igniter will be available through the inverter (AC SBY Bus). Is this correct?
So putting the Start Switches to Flight or selecting the R - Igniter with Start Switches in CONT has the same effect?
