Apart from spelling 'creative' incorrectly when using the Pedant Alert :-)
It's not creative at all.
The sentence is one to curtail your freedoms, there are several ways of acheiving this, only one of which involves actually locking you up.
There is also being required to report to a Police Station daily, surrender of your passport, or electronic tagging to name but 3.
The sentence might also be a community order, and you must then perform supervised community service for a set number of hours, which also curtails your freedom.
A conditional discharge may even contain the condition that you report to a Police Station periodically.
