I cant help but wonder!

Hi guys! Hope we all are having a great sunny summer! Left for me, i did be vacationing somewhere far from home in some nice well tendered beach...
"if only wishes were horses"
So i had this experience i wanted to share with you guys as it has left me wondering more at this almighty google!
Usually i publish my posts through sitecontent and then edit in wordpress to add the neccesary images and links and all formating that needs to be done.
So a few days ago, i published a post and edited in wordpress , and whilst in the process of editing , i got called away and had to abandon the work half way through. On getting back to finish up the work, i realised i had new notifications, and they were for my content being indexed, but to my greatest surprise this very post i was editing was one of them! I mean how is that even possible!

That is a question i have been asking myself since then, how is that possible? Or does it mean google now crawls our work in progress, or the fact that it is under editing does not matter?
I am just baffled and thought i should share with you guys, just incase someone else has experienced such, or can give me better explanation to that.
Thank you all for your time and remain richly blessed.
Queen.
