This is perfectly normal. My 2017 BMW 440i GC also received full reprogramming after I reported a minor problem with iDrive. Most of the time, when the dealer reprograms the vehicle without any specific problem reported by the customer, the softwares changes are mainly internal improvements, for example better diagnostic logic.
Imagine BMW dealer trying to diagnose the root cause for the same problem in two F3x vehicles but two years apart: 2016 and 2018. The 2016 vehicle has older ECU software and functionally different diagnostic logic. It's in BMW best interest to have the same software release in both vehicles: saves time and money on warranty repairs. To the extent permitted by the hardware components, it's simply beneficial to have the same software at any given time.

He just said that i have “version 2” and the it needs updated to “version 4”.
I asked this because i read on some forums that some were experiencing lose in exhaust sounds etc. And my paranoia activated.

"This Service Action involves approximately 30,162 vehicles produced from 7/26/2016 to 11/29/2018."
"In the DME control unit software, a function to protect components was incorrectly implemented. This
function should protect internal engine components, in case the engine is run at high speed for too long when
stationary."

When driving the car you could easily get past 5000 (although not a lot of point in that engine). So I suspect this function has been around for a while, just implemented differently according to the engine .
