Perhaps so.  Last night I saw a triple glint from 25172 = 98-10D =
Ir P47  53/50, peak-peak-peak duration 37.86 s, and a quadruple glint
from 25170 = 98-10B = Ir P48  56, peak-peak-peak-peak 40.40 s.
Typically, the triple glint was not so very shallow as the quadruple
glint.

I think of these multiple glints as maybe a bit like growing very long
fingernails or something like that.  It is a neat experience, but there is
a downside. As the number of peaks increases, it seems their amplitude
shrinks to the point where "who cares? .2 mag, big deal".  And worse, they
become hard to distinguish from atmospheric "seeing".  But they are very
neat. 

Cheers.

Did you know?:
EGP, USA 32, USA 81, TiPS, NOSS 2-1, NOSS 2-2 and NOSS 2-3 are interesting
objects?  Don't be fooled by dimness.  Watch these in binocs.  You'll most
probably be rewarded.
