Some instruction opcodes have an entirely different encoding when a VEX prefix is present. For example, 0f41 is CMOVNO without mandatory prefixes while VEX.NP.W0.L1.0f41 is KANDW with a mandatory prefix. To avoid collisions, the VEX prefix is better handled as a completely separate decode tree, at the cost of a slight increase in table size.
