I believe this is not merely "technical", but from a physics standpoint it is correct. Any mu- that stops in a material is captured by some nucleus in a time that is short compared to the free muon lifetime. The lifetime of a captured muon is shorter than that of a free muon (~864 ns when bound to Al, and shorter still for higher Z), so this has an important effect on the decay lifetime.

Of course this does not apply to mu+. For it, electron capture to muonium is possible, bur rather rare.
