It is hard to say if it is paradoxical. However, I think the considerations are different in the context of a minimum sentence. I will give you an example.
In the bail context, the reverse onuses that relate to firearms are very closely tied to the grounds for detention. A crime that is alleged to have involved the use of a firearm in a robbery or a sexual assault is presumptively seen as something that poses a public safety risk. It's closely linked to that just cause...the three grounds of detention.
There may be a tendency to want to try to make comparisons between considerations at the bail stage and considerations at the sentencing stage. The charter rights are different in those stages, and the purposes of those different processes are different.
