Question Regarding iPhone Restart with Apple Watch App Still Turned On

I am currently in the process of developing an iPhone app along with its corresponding Apple Watch app. After turning on both apps, I proceed to terminate them completely. However, when I solely turn on the Watch app, I can see the splash screen running smoothly on the Watch screen. Strangely, when I turn on iPhone app(the watch app is running), there are times when the iPhone app's splash screen appears to be skipped(this behavior is not consistent.)

Upon experimenting and changing the order of app launches (iPhone app first, followed by the Watch app), the splash screen of the Watch app is never skipped. I'm curious to understand the reason behind this behavior. Could someone shed some light on why this is happening? Any insights would be greatly appreciated!

Can you please elaborate more on what you mean by "splash screen"?
