Yes and no – the number of playable lines does not necessarily tell us how "obvious" those lines are to find for a human.
To give a trivial example, if I take your queen, then recapturing my queen is almost always the single playable move. But it's also a line that you will easily find!
Conversely, in a complex tactical position, (even) multiple saving moves could all be very tricky for a human to calculate.
