double double trouble

Recently, the word "double" has been doubled. In meaning, that is. It
has been applied to two different phenomena.
1) Multiple satellites: Two different satellites which glint at the same
time.
2) Multiple glints: A single satellite which glints at different times
during a single pass.
There is a third phenomenon which I observed very recently, perhaps a 1a)
phenomenon: Two different satellites in the same field of view at the
same time which glint at different times without any overlap.
I think careful observers should have the vocabulary to distinguish these.
I suggest that double should be reserved for phenomena of type 2), where
only a single satellite is glinting. Triple, quadruple, etc., follow
naturally.
I would suggest that the term "paired" be used for type 1), but then what
could be used to describe the early post-launch OBS where more than 2 can
be glinting at the same time? Tripletted? Can someone suggest something
better?
Any suggestions?
Cheers.
