They brought a grammaticalization product into the adopting language, which had occurred in the contact language, by copying polysemy in the contact language between the grammaticalized and pre-grammaticalization interpretations of a speech form.
As for mechanisms of contact-induced influence (Thomason 2001 : 129-156), one can find both unconscious negotiation of structural features between the contact languages and conscious decision-making.
