Re-grilling Flanks Adds Juiciness?

Q.  Dr. BBQ:

 

I was watching my friend cook BBQ flank steaks and he put the done meat back on the grill right before serving to “juice em up.”  Is this for real?  My thoughts are they will just cook a little more and probably lose a little “juice”  rather than do any good.

A. Hi John,

I’m with you, all that’s going to do is dry them up. A little rest is a good thing, but I’ve never heard of any such thing as “juicing them up.”
