There are 3 diff lipo charge modes - charge mode (no balancing) lipo balance mode (balances while charging), lipo storage mode (charges to storage voltage) and lipo fast charge mode. Only the fast lipo charge mode is limited to 1C. If you look at the manual, pg 17 you'll see the charge rate mentioned as settable from 0.1 - 10amps.
The reason for a FAST lipo charge mode is to reduce time, so it seems stupid to me to impose this limitation, especially if you have a high C charge capable lipo. They do this by shortening the CV part of the lipo charge protocol.
So to answer your question, no it doesn't change anything, the X2 is still a more capable, more powerful charger.
