The picture shown is a stand pipe in a hotel. I went to ice in the hotel I was staying in and this was right next to the ice machine.

Additionally, if we did get connected with hose only, there would certainly be a kink at the coupling, further reducing our pressure.
When these systems are designed they are equipment specific. Meaning that the flow points are determined by the type of cooking appliance and its location under the hood and suppression system. Moving or replacing any appliance requires reevaluation of the system and could mean an alteration to keep the system adequate.
