no. you cannot do this. $sel1 and $sel2 simply contain
strings (which are the names of automatically generated
procedures, i.e. atomselect0, atomselect1, etc.).

what you can try is to create a new selection with the
combined selection string (make sure that $sel1 and $sel2
point to the same molecule).

set sel3 [atomselect [$sel1 molid] "([$sel1 text]) or ([$sel2 text])"]
