I've never really liked Mathematica's handling of which functions may be
passed assumptions, or may be used (effectively) in Assuming...
Assuming[a > 0, Limit[Exp[(-a)*t], t -> Infinity]]
0
Similarly,
Assuming[a < 0, Limit[Exp[(a)*t], t -> Infinity]]
0
I can't really answer the question, but I can offer those alternatives
to get the assumed limit.
Cheers,
C.O.
