Yes, but the speaker's conversational strategies in terms of syntactic construction (front focus) and rising pitch inform the audience that there is more information to come thus holding the floor. This further supports the function of the text as the speech is designed to commemorate the endless heroic attributes the corporal had exemplified in Afghanistan.
Hm, I'd be careful of calling it holding the floor though. She's not really doing it to hold the floor; the turns are scripted and it is only she who is speaking. I agree that it does signal an incomplete utterance/ that there is more to come, but personally I don't think it's the best thing to talk about. It's difficult to tie to formality imo, but maybe that's just me.
Not sure if the example of front focus is good to talk about here either. Front focus, whilst a part of information flow which is discourse, is also syntax. Not sure if she fronts 'with the medal' for the purposes of signalling that more information is to come either. imo it's more to emphasis the medal and to shift the topic back to the medal itself, allowing her to close off the speech nicely and actually award the Victorian Cross to the corporal after providing some background info about his heroics.
