Doubts about AN4013 and timer gated mode

Hello,

an4013 Rev. 6 on page 21 writes:

"The Counter Enable signal is generated by a logic OR between CEN control bit and the trigger input when configured in gated mode."

while e.g. RM0351 writes:

"Enable the counter by writing CEN=1 in the TIMx_CR1 register (in gated mode, the

 counter doesn't start if CEN=0, whatever is the trigger input level)."

This contradicts and probably AN4013 is wrong and should read "logic AND"
