They're not equal, look at bytecode.
prevMessage?.text += line is the same as (in pseudocode)
return if(prevMessage != null) prevMessage.text.plusEquals(line) else null.plusEquals(line)
whereas prevMessage?.apply { text += line } is the same as
return if (prevMessage != null) prevMessage.text.plusEquals(line) else null
