Question about null-safe call on nullable property...

Question about null-safe call on nullable property. In our team we were discussing null-safety topic and wondering how kotlin .? works. So we decompiled it using AndroidStudio. The outcome was unexpected for us.
The class:

class NullSafeCall {

    var nullableString: String? = null

    fun nullSafe() {
        nullableString?.length
    }
}

Decompiled nullSafe method:

public final void nullSafe() {
      String var10000 = this.nullableString;
      if (this.nullableString != null) {
         var10000.length();
      }
   }

It looks to me it can still get NPE as a result of nasty race-condition. Can someone explain to me wether it’ s kotlin issue or decompiler output is not quite accurate.

I think the decompiler is wrong. The bytecode looks ok to me
