It doesn't make any sense for Susano'o to have simply been pushed back by Hirudora. Or for Madara to have simply deactivated his Susano'o and hang back. Besides the fact that the Mokuton binding Bee and Guy was weakened after he got hit, there's also the fact that Madara said himself that

. With that mindset he goes on to take care of the Naruto clone, and gets a Hirudora to the face. Then two chapters later he ends up

. If he had a mindset of capturing Bee and Naruto before the Juubi was revived, then it makes no sense for him to deactivate his Susano'o, sit down, and do absolutely nothing while Obito (the only one who could resurrect him) could have been possibly double-teamed by the Jinchurikis he was trying to capture.
Thus the more likely explanation for why Madara, despite no longer playing around and wanting to capture Bee and Naruto, was not seen until the Juubi was revived could simply have been that he was spending all that time regenerating from having his Susano'o busted by Hirudora. Any explanation involving him willingly deactivating his Susano'o and just lazing around would not make sense with the mindset that he had.
Besides that, a tired, worn out Guy was fast enough to grab Kakashi and outspeed an attack that is faster than Kamui while he was in Gate 5 or 6 (most likely Gate 5 as that one gives him the aura he was seen with while leaving his pupils intact, whereas Gate 6 gives him the aura and makes him lose his pupils). That easily puts him in the same ballpark of speed as V1 A, who was unable to blitz Obito. That means he would be even faster in Gate 6. While it's debatable whether he would be fast enough to dodge Amaterasu in Gate 6, it's not debatable that he would be able to do it in Gate 7.
Base Minato was able to react to Ay's full powered strike twice. On the other hand, a Minato in Sage Mode (which is explicitly stated to

) was unable to react to Madara, which heavily implies Madara was much faster than V2 Ay. That same Madara was

by Guy's 7th Gated speed, and he was unable to move fast enough to sever Guy's arms during his assault like he did with Minato. The only time he was able to get an attack in was when Guy took a moment to prep Hirudora, and even then, the mere fact that Guy still had arms after Madara attacked implies that he was only able to land his attack after Guy launched Hirudora. That puts 7th Gated Guy as much faster than V2 Ay, and thus, much faster than Amaterasu.
At any rate, if he gets caught in Amaterasu before he reaches the 7th Gate, Guy has the pain tolerance to simply release the 7th Gate, which would generate enough force [

] to blast the flames off of him, just like Shinra Tensei did for Nagato. This is also possible with the release of the 6th Gate (which blasted a hole all the way to the surface of Kisame's lake, destroying his sharks in the process).
He also has the stamina to launch Hirudora more than once if a tired, worn out Guy with a broken arm and cracked ribs can open the 8th Gate and keep on fighting through the pain that was wrecking him (and that was after using two other Hirudoras that day). Thus Guy goes into the 7th Gate, dodges Sasuke's attempts with Amaterasu, slams a Hirudora in him, then another one for good measure if the first one fails to kill him (but it will bust his Susano'o).
