Does the maxout period for L1 get reset even if we leave US and re enter US after one year with the SAME VISA ?

Question is - Does the maxout period for L1 get reset even if we leave US and re enter US after one year with the SAME VISA ? Or maxout period RESET is applicable only if we re enter US after one year with a NEW VISA OR NEW PETITION ?

In my case I stayed in US as detailed:

1st Entry: May 2010 to April 2011 - 11 months (L1B Blanket VISA 1).

2nd Entry: September 2012 (In same Blanket L1B VISA1). This entry is more that 365 days from 1st exit but I re entered US on the same L1B VISA1.

Then got my new L1B blanket VISA2 stamped from Canada and have been staying since then with (1 or 2 months outside US for vacation).

Question is: What will be my L1B maxout period - 2017 (5 years from VISA2) or 2016 (VISA1 11 Months + VISA2 maxed to 5 years) ?

Can anyone answer this question
