Please can you explain the function of "any runner" in the "Selection Conditions > Min/Max Selection Price" settings.

I know it probably seems obvious but I feel like I must be using it incorrectly.

For example,
I have a strategy where there are three possible selections but I only want them to place bets when the lay prices are between 2 and 4.
If I create a single condition with "Selection Conditions > Min/Max Selection Price" and select "any runner"... then no bets ever get placed.
I need to create a seperate condition, for each possible selection, in order for bets to get placed.

It's not a big problem... I just don't understand why it is.
