No it doesn't...It infers that he was aware of at least one trumpet that would be blown numerous times...Rather than debate it here's a page with an explanation that handles the debate much better than I could...If you are interested...
I don’t see how you get one trumpet blown numerous times from “last trump”. You can’t have a “last trump” without previous trumps, and the fact that a specific event is said to occur at the same time as that “last trump” means that this trumpet must sound at one specific time, other than multiple times. If it was blown multiple times, then you would have to have multiple “raptures”, otherwise the prophecy is false. There’s really no logically getting around that.
