L1 B - H1 Approval POE Travel Query

[jawa]

I'm now working on L1 B visa, applied for H1 this year. Mine was picked in lottery, I heard mostly the approvals can happen any time before October.
I have travel plans to my home country (India) for a month between August - September. If I get approval for H1 before my return to US, will there be any problems at POE?
I want to travel back with my L1B instead of going for H1B stamping. Please suggest.
