Unfortunately a small but significant percentage of flight crew are obsessed about maintaining high speed and direct routings even when the situation clearly doesn't favour it.
Obviously impossible to comment on this example without seeing an exact transcript of the RT. (and maybe the cvr!)
But broadly you might want to prepare yourself for the fact that if you say anything remotely ambiguous it will, by this small percentage, be interpreted as faster / more direct. When it comes to descent and speed reduction, you could do worse then add the word 'now' even if strictly speaking it is not required by standard RT.
(standard rt could probably do with an overhaul in regards to descent and speed control, but I've been saying this for years).
