Re-Entry if companies L1 blanket petition going to expire

[SVRR]

Hi,

Blanket Expiry : 09/Jul/2017
I-94 Expiry : 29/Jul/2019
PED: 07/Jul/2017. 

My company's blanket is expiring on 07/Jul/19 & it's renewed couple of days back, I have situation that I have to go abroad, now my company is asking me to apply a new Visa before I enter (return 04/Jul/17) otherwise i may get the i-94 until OLD PED expiry (07/Jul/19) ?? 
or 
Will I get the I-94 till my Visa expiry ?? 

Appreciate your help.
