Yes, that's precisely what this line implies. Shanks literally lost an arm to save Luffy, there is no reason to think that he wouldn't come to save the giant even if there is a greater force at play (which is debatable btw)
Which is non relevant to begin with. Bonney and her Dad wouldn't be safer on the Sunny than on Elbaf. The motherflame seems to be mobile and can annihilate an enormous zone at once. If Imu wishes to annihilate the Island where the strawhats are standing on, they can do it no matter.
What I say is that Vegapunk is used to make failsafe in his inventions, so its not impossible at all that he installed one on the motherflame.
