I interpret the instruction to be profile descent speed below 10000' until the normal slow down point to meet my companies speed restrictions.
I think I know where your heading with your question, it is not a clearance to operate max speed above and below 10000'. That is covered with the phrase"maintain max speed above and below 10000 cancel STAR speed restrictions". If you are not given a clearance to descend at maximum speed then the requirement is to descend at profile.
