two NVT4858 use question

I plan to use two NVT4858s between HOST and SD CARD. A

Host (Our SOC) >>>> NVT4858(1.8V to 3.3V) >>> SD CARD 

DATA[3:0], CMD, DQS, LPBK signals synchronized to CLK are required.

So I plan to use two NVT4858s.

NVT4858 #1 : CLK, CMD, DATA[3:0]

NVT4858 #2: DQS, LPBK

Is there a critical issue with the timing difference between the two separate level shifters?

All signals are synchronized to CLOCK.
