What is the runway holding short line on Taxiway B between B2 and B3 at KFAT for RWY29L? At Fresno Yosemite International Airport (KFAT), I was instructed to taxi to RWY 29L via B11, B from Signature Support. When passing B3 and approaching RWY 29L end, I noticed there is one holding short line between B2 and B3 and the next one is on B2, I was confused where to hold short for the instruction (hold at the first anyways). 

The one between B2 and B3 seems extra, but it is a double-solid-double-dashed line, which is also shown the Google Map the same I observed. I am wondering how this can well-define a runway protection area? Meanwhile, the first holding short line (the one between B2 and B3) does not mark which runway it protects. I also suspect it should have been ILS protection marking instead.

That’s a hold line for aircraft taxiing on Bravo while large aircraft are departing Rwy 29L to prevent aircraft from taxiing behind the blast pad for 29L and potentially being tossed around by the jet blast from the departing aircraft.
